Answer: l = P/2 - w
Step-by-step explanation:
Perimeter formula for rectangle :
P = 2( l + w )
We have to write l in terms of P and W.
P/2 = ( l + w)
P/2 - w = l
Now, flip the equation and you'll get :
l = P/2 - w

First, add all the numbers together. 
Divide by the amount of numbers. 
is the closest, so that is the answer.
4x+13=5x-12
-4x. +12
25=x
3(25)-8=4y+7
75-8=4y+7
67=4y +7
-7
60=4y
y=15
lol i know this is correct bc this was a problem on my homework a couple days ago and i got it right
