2L + 2w = 112 ---> L + w = 56 ---> w = 56- L
Area = L*w = L(56-L) = 735
56L - L^2 = 735
0 = L^2 - 56L + 735
0 = (L - 21)(L - 35)
THe dimensions of the rectangle are 35 x 21
Distribute the 2 to all terms within the parenthesis
2(x + 8) = 2x + 16
2x + 16 = x + 20
Isolate the x. Subtract x from both sides and 16
2x (-x) + 16 (-16) = x (-x) + 20 (-16)
2x - x = 20 - 16
Simplify. Combine like terms.
x = 4
C. 4 is your answer

Answer:
18%
Step-by-step explanation:
Non fiction books - 72
