Answer:
what is ac?
Step-by-step explanation:
1.
area = L x w = 72
L = 2w
72 = 2w*w = 2w^2
divide by 2
36 = w^2
w = sqrt(36) = 6
l = 2*6 =12
perimeter = 2L +2W = 2*12 + 2*6 = 24+12 = 36
2.
sqrt(40)= 6.324555 cm ( round to 6.32 )
6.32 - 4 = 2.32 cm original length of a side
4(-2y + 16) + 8y = 32
-8y + 64 + 8y = 32
64 = 32
Answer: no solution
If i did it right the anwser is 20
