How are you supposed to solve this?

>>

Its 3y+2

>>

>>26311954

it wants it without variables. That cant be right.

>>

>>26311913

38?

You should take you're shit to >>>/sci/ they know better and they love to do middleschoolers homework.

two opposite sides of a rectangle have to be the same length, so you know the other two sides are also 3y+2 and 2y, respectively. add up all the sides, and you'll get 10y+4. you're given the perimeter, so you know 10y+4 = 124. solve for y and then plug the value of y into the formula for segment ab

>>

2(3y+2)+2(2y)=124

10y+4=124

10y=120

y=12

AB=3y+2=3(12)+2=38

>>26311913

lol literally did this in my head

>>

>>26311913

Its 38 senpai.

You know the perimeter = 124.

You also know the perimeter = 10y + 4

Solve for y.

Fuck off Martin Shkreli

>>

>>26311913

124=2(3y+2)+4y

124=10y+4

120=10y

Y=12

3(12)+2=38

38

>mfw I thought it said "Is below 124"

>Mfw thinking there are a lot of possible solutions to this problem

>mfw only realized I was wrong when I read the thread

Maybe this is why I don't do math

what?

>>26312022

That's wrong because it's not a perfect square

Martin Shrekeli is the Muhammad Ali of business, he started ffrom the ground up with only $1.00 in his pocket, he used this to buy a pack of gum, then sold each stick on the street corner at 15c each, making $3.00 a pack, soon he moved on to larger ticket items including buying intellecual property including the cures to cancer and herpes (which he destroyed, because curing cancer will increase lifespans to an unsustainable level, carbon-wise, and the herpes cure because he wants to know who the whores are) he himself remains a virgin because he's saving himself for marriage, and he refuses to marry until he finds a woman who equals him in every way, which is proving difficult. Also he is a known mathematical genius who has proced many theorems including the Barbsberry Problem and Gray Space. He also has been known to brag about his math skills on 4chan

Well your questions has been answered, is it indeed 38. You solve it by adding all the sides and making that equal to 124, then getting y. And plugging y in the equation.

Are you from middle school or American?

college, taking intermediate algebra

Damn. This is 7th grade level algebra

Lel i want this to be true so bad

We know that the perimeter of a rectangle is the sum of all its sides

We know the CB side is 2y long

We know the AB side is 3y +2 long

We know the perimeter = 2(CB) + 2(AB) from the definition of a rectangle

We know the total perimeter = 124

therefore:

124 = 2(2y) + 2(3y+2)

>distribute parentheses

124 = 4y + 6y + 4

>combine like terms

124 = 10y + 4

>subtract 4 from both sides

120 = 10y

>solve for y by dividing both sides by 12

y = 12

we've found y, now we just need to plug it in for AB

AB = 3(12) + 2

AB = 36 + 2

AB = 38
