Question

The area of a rectangle is 60 square inches. The length of the rectangle is 7 inches longer than the width.

Which equation models this situation?


w + 7w = 60


7w = 60


w + 7 = 60


w(w+7)=60

Answer 1

w( w + 7 ) = 60

Answer 2

I think

Answer 3

if you use that one, you will end up with \[w^2+7w=60\]
this solution would leave you with more work to do. i think it's the first one

Answer 4

cause when you add w and 7w, you would get 8w
then you divide both sides by 8 to get w by itself

Answer 5

oh

Answer 6

You have a point

Answer 7

after you dived both sides by 8, you should end up with w=7.5 if my math is correct

Answer 8

@hallyramos12 I agree with your original answer.

if w = width, then "The length of the rectangle is 7 inches longer than the width." means that l = w + 7

length*width = area ---> w(w+7) = 60 which is in agreement with choice 4
