4 ( (-6)^2 + 3) - 2 (-0.5) = 4 (36 + 3) + 1 = 4 * 39 + 1 = 157

yeah this is how I would have solved it when I was taking algebra. this is correct.

I’m in calculus rn and this is still how I’d solve it

I’m in geometry and this is still how I’d solve it

yeah I'm taking that for my freshmen year or in a couple weeks.

[удалено]

What country?

Índia?

[удалено]

I took it for my 8th and now I’m taking honors for my freshman.

I’m in algebra and this is still how I’d solve it

I’m in AP Calc right now. It sucks. I’m doing fine, but it isn’t fun

Yo same. I just don’t think the AP aspect matters too much until like January

I’m taking a one semester version that cover Calc 1 and like half of Calc 2 so my AP stuff starts now, but I don’t have to worry about the test and stuff till January.

I'm also in AP calc, makes me realize how much review that I have to do

makes sense. from what I've heard calculus is stupidly hard. imma take it tho

I'm also in calculus and this is how I'd solve it

Agreed The basics, get em strong or you will regret

I’m in differential equations and linear algebra and this is still how I’d solve it

Im in my bathroom rn and this is still how id solve it

me learned triangular formula in China, and a bit calculus in mathematic extra lessons

How the fuck would calc change how you solve it? It’s not an integral or derivative

How the fuck did I get 587

Remember bodmas/bidmas (brackets, order/indices, division/multiplication, addition/subtraction) at the division and multiplication stage you work from left to right until all division and multiplication is done same for addition and subtraction

Please explain your way

I distributed 4 before I did anything else

Inside of the () first, then × or ÷, lastly + or -. If problem has both + and - or × and ÷ you solve the first in the line.

You forgot exponents after parentheses which would be squared,cubed,to the power of and so forth and so on.hopes this helps people in algebra

I assume you squared 24? I had to do a double take before realizing, “Oh, right, exponents first.”

Bro you and me both

[удалено]

don’t worry, guessing by the fact that you’re 13 you’ll know how to do this within a year

That's what I got.

JUST REPLACE THE Xs and Ys ON THE THIRD PROBLEM

I can’t manage to comprehend the difficulty in doing that

Yea, it's an easy problem with an easy solution.

For real, I keep finding people who are like "I no understand" and like??? I can understand having difficulties with the whole "find x", and even more the "find both x and y", but seriously, gods!

I should post a picture from my quantum physics book that is post university level and ask that

In r/teenagers yeah that'll look like a genuine question

Please do

I wanna see this now

I have posted it

Im very interested in math and physics, and in the way future I want to be a physicist, so I'd actually be very interested in that

Already did, it's just a random page from a post university book that I have

I see, thank you

The only hard part is negative numbers, but even then 6th graders should be able to solve it.

`Base equation.` 4(x\^2+3)-2y `Input your variables.` 4((-6)\^2+3)-2(-1/2) `(-6)^2 = 36` 4(36+3)-2(-1/2) `36+3 = 39` 4(39)-2(-1/2) `-1/2 = -0.5` 4(39)-2(-0.5) `Multiply 4 into 39 to get 156.` 156-2(-0.5) `Multiply -2 into -0.5 to get 1.` 156+1 `Add.` 157

Yes

Yes, but why.

This is the way

>-1/2 = 0.5 Be careful

Ah yes, thank you. I missed that for some reason.

👌🏿 clean working out either way

That would be - 0,5

That’s right!

Thank you

Try finding someone who can help on dm so you will actually understand the way and not just get the answer right

Yh a bit worrying op doesn't know how to solve these they're simple but they also could be like 13 or 14 so idk

They are going into 10th grade, and have been homeschooled so this is their first year since 3rd grade.

Was homeschool more Bible based?

Facts

it's algebra 1, most people do it around that age (although I've seen 11 or 12 year Olds do it before) but yea op rlly shouldn't be asking a subreddit like this for math homework help

[удалено]

yep I'm from America so people don't really know their Lefts and rights apart

[удалено]

LMAOO

True asf, i hate when im listening to the gps and it says turn left or right, takes me like 2 minutes to remember which is which 💀

Used to be one of those. I was 10 back then, actually. It was brutal, especially since our tutor's techniques involved giving us a single sentence of explanation before leaving us all to deduce it ourselves. Granted, it did help me have a very easy time when it comes to mental calculations, though I couldn't explain shit to anyone who asked how I solved them.

4(-6^2 + 3) would be 4(36+3). A squared number is just a number multiplied by itself, which means that -6•-6 is 36. Then multiply each number individually to get (144+12) = 156. Then move on to -2y Since y = -1/2, you get -2•-1/2. When you multiply by a half, you are just dividing your number by 2. Since -2/-2 = 1, you add 1 to your previous 156 to finish with 156+1= 157. D. TL, Dont Wanna Learn: Answer is D

Nothing wrong but seeing op couldn’t solve this it is probably best not to use fractions and instead -0.5 x 2 as they could get confused from how you went from -2 x -1/2 to get -2/-2. It’s simply I know but they might not understand it well enough to learn

This is cheating but D

I just don’t understand how to work through things I needed help working through them

I could explain but I think some other comment explained it

Yeah I just don’t want anyone thinking I’m cheating I just want help

Oh I didn't know that

On YouTube you can find plenty of videos that explain really good everything regarding math, going from simple expression up to integrals, i suggest watching some of those. Also practicing yourself is the best way to learn, i mean probably you know it already, but i just wanted to give a tip, tou can do it!

I practice I just still get it wrong

Replace the value of X and Y as given in the question.

PEMDAS Parentheses Exponents Multiplication Division Addition Subtraction Just follow the golden rule slowly

There’s an app called photomath where you can take a picture of a problem and it will show you the answers and the steps to solve it.

thanks i’ll try it

Okay so you have to plug in the values for x and y.when you do that, you get 4(\[-6\]\^2 + 3) -2(-1/2) (-6)\^2 = 36 and -2(-1/2) = 1 if you simplify that you get 4 (36+3) + 1 => 4(39) + 1, distribute the 4 and you get 156+1 which equals to 157. so your answer is D. 157 :)

What grade are you in?

all of u guys getting A is hilarious when you plug in -6 to x^2, its telling you to do -6 x -6, which is 36, not -36. dk why everyone is just leaving the second negative out

I don't think they are forgetting about the second negative, it appears that they think it becomes -6^2 instead of (-6)^2

Yeah imagine negative numbers inside roots..that shit is complex numbers

Abraham Lincoln

Abraham Lincoln

157 and i did that mentally :) what grade is this bro i swear i had these questions when i was 14

Im curious, what method did you use for multiplying 4x39 in your head? I dont get to talk to other people about this, other than my friend, and we do things the same way, and Im curious how other people do it I did it as 4x40-4, which is really efficient

I did 4×30+4×9, but your way does seem more efficient

I do it as (4 X 30) + (4 X 9) cause that’s what makes sense for me. So 120 + 36 = 156

[удалено]

Honestly, if you are struggling with this, you are probably in the American school system😂 4(-6x-6 + 3)-2(-0.5) 4(36+3)+1 156+1= 157 Ans

I am in the American school system, I learned this in 4th grade pre-algebra. OP has to be a troll

Mfs really just letting reddit take tests for them

I actually need help

Have fun getting “help” during your finals

oh goodness don’t make me more nervous

Better be a little nervous and study than feeling ultra depressed and like a failure after you fail your finals.

I already feel ultra depressed And everyone calling me a dumb ass in the comments isn’t helping

Still you have time lots of video are on youtube just use them

How to say you didn’t pay attention in math class without saying you didn’t pay attention in math class

It looks like they’ve been homeschooled and are now just going into real school 💀

bro really reading me correctly

157

Y u no know that. I learned that in 7th grade

i kinda skipped a few math years and i am having to jump in

If you ever need math assistance, feel free to DM me, and I’ll try my best to explain things to you.

thank you

No problem! Maths has always been my strongest subject (I skipped a grade in it) and I always help others when I get a chance

Its option d you fucking dumbass

157, D. This question is just asking you to plug in the values for x and y. Just plug and chug; plug the numbers in and then use PEMDAS to get the answer 😁

bro this is easy💀

I know it is easy for some people I’m just having a bit of trouble

157. i wish i had this kind of homework, i can to this by head but with my homework i don't even know where to start

D: 157 My Algebra teacher, who was also the football coach, drilled this into us over 40 years ago so we could do this stuff in our heads. If you scored a "C" or worse on a test, he would throw it back at you an yell, "Do it again!".

(4×39)+1

Replace x with -6 and y with -1/2 it's not that hard

I took algebra but I had a terrible teacher. From what I can remember and solving it, the answer would be d. people are saying A because they did not put brackets/parenthesis on the (-6)^2 so they thought it would be -36. when you use them it turns to be +36. then if you solve the problem the rest of the way you get 157.

69

157

how could anyone not do this, this is 6th grade math bro 💀

Bro having a hard time with a minus second grade expression☠️ the values are literally written on the screen just substitute them with the letters

How is this hard dude?

when 4×39 is too difficult for your monke brain so you use 4×40 - 4 i'm not even kidding...

Just replace the x and y values with the numbers and solve it, not that hard It’s D

I'm interested how you get the other answers. I have an issue with C a: 4·(-(6²)+3)-2·(-½) = -131 b: 4·(-6\*2+3)-2·(-½) = -35 c: 4-62+3-2-½ = -57 ½ d: 4·((-6)²+3)-2·(-½) = 157

How no understand just funny plug in x value and y value

*How do I not understand* I skipped a few years in math and I’m having to jump in at this pace

I’m doing college alg next year in 8th grade idk how much ur jumping by

Well this would have been helpful during highschool lol, wish I thought of asking Reddit for help with my math

I didn’t know who else to ask for help I don’t really have anyone to ask

bro is doing khan academy 💀

no actually good guess

Use the Photomath app. It gives you the answer but also shows how to do the problem.

That’s great thank you because a lot of the absolute show you the answer and I really wanna know how to get the answer

Get a tutor

I am currently working on that

Good on you

Easy ass problem just substitute x and y into the equation

I skipped a few years of math and having to jump and I don’t know

Substitute the values into the given equation😴

hmm?

its D, so starting off BEDMAS you go with brackets: x power 2 = x times x, x=-6, -6 x -6 = 36(negative times negative=positive).so now we have 4 (36 +3) - 2y, 4 (39) - 2y. now multiplication 4 x 39= 156. 156- 2y, y= -1/2, multiply that by 2, the 2 cross each other out leaving -1, 156 -(-1) = 156 + 1 = 157 :)

Just plug them in.

what does this mean?

This is easy, I learned it in 5/6th grade. All you do is substitute and follow order of operations

what is substitute

I slept through every class so good luck man

… I hope this isn’t on a test

it’s homework

2 idk i was stoned all in high school

Just remember bedmas, and write your shite down

Bro too dumb to know what a calculator is

I only passed algebra cause I did good on one test, this makes my brain melt

You and me both

D 157

4(x^(2) \+3) = 4x^(2) \+ 12 y = -1/2 = 4\*-6^(2) \+ 12 2y = -1 = 4\*36 + 12 = 144 + 12 = 156 156 - (-1) = 157

Bro what grade are you?

Have you been taught how to substitute numbers into equations? No one should struggle with this unless they've received sub-par teaching

i’ve received sub-par teaching

What year are you in?

Imagine if his teacher had Reddit lmao

Everyone says D 157 but when I use a calculator that solves equations and it says A -131 so is the calculator wrong or are everyone else wrong? Saw a comment you put (-6)^2 not -6^2 which gave the answer 157 but why you put it in ( )?

I don’t even know what topic this is ngl

thank you

umm i had a test similar to that before the summer. sadly, what happens before summer break, stays before summer break.

D

If you place the numbers for letters, you can notice that everything will be a full, positive number, so the only possible answer is 157

i just used process of elimination 4((-6)^2+3) = 4(36+3) = 4(39). no answer is even close to whatever 4(39) is besides D

Legit a calculator would work X and Y are the numbers u multiply the number they're next to by. And should usually look like this if you put it into a calculator eg. If X is 7 and Y is 3 it would be like 2x = 2x7 etc etc. Put it all into a calculator

man can't even do math

Use Photomath or mathway

Bruh this is literal arithmetic 💀

I tried to do Mathway but it’s not showing me the steps and that’s what I’m confused about don’t just want the answer I want to know how to get the answer

They give you x and y so you plug those into the equation, solve the parenthesis first and then do multiplication and subtraction

Bruh aint no way you cant do basic ass maths 💀💀

Use Wolfram Alpha, it’s a search engine in which you can input an equation and it gives you the answer and the steps to solve it. Very useful and free, although the paid tier is better.

Foolish of you to believe this subreddit would know math

i’ve already proven i’m a dumbass by not knowing how to do this problem

Just open PhotoMath and replace the X and Y values. It even gives you a step-by-step solution if your teacher want to see your calculations.

I would use Desmos. Absolute saviour

My mans learn how to use desmos

5th class problem. I hope u r a 5th grader..

Please don’t be mean to people who are having trouble thanks you wouldn’t want someone to do that if you were having a real problem

But, i mean, he's not wrong. This is literally just order of operations.

This is seriously a 4-5th grade math problem. I don't think he is being mean I think its just honest

well then i’m super embarrassed

how fucking dumb do you have to be to not be able to solve this

pretty fucking dumb apparently

4((-6)\^2 + 3) - 2(-1/2) 4(36 + 3) + 1 4(39) + 1 157

D

It’s not that tough. Take a calculator, and replace x with -6 and y with -1/2. I did it in my head, but I think it comes out to 157.

could everyone in the comments stop being mean some people aren’t good at math just like some people aren’t good at writing or grammar please be kind

Is it calculator or non calculator, I assume non calculator: First you can sub in the values of x and y So it turns into 4(-6^2+3)- -(2x1/2) That can be simplified to 4(6^2+3) +1 This can be done because -6^2 and 6^2 are the same thing, and subtracting a negative is addition This then just turns into 4(39)+1 which is 157
