Solve for u -8u + 6 (u+7) = 28 simplify your answer as much as possible.

u=7

Step-by-step explanation:

First multiply 6 by u and 7 to get 6u+7

next add  -8u + 6u and get -2u

then subtract 42 from both sides of the equation (28-42)

finally divide -2u from both sides of the equation and get 7

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36
