Answer:
f(a) = 2a^2 + 4a + 5
Step-by-step explanation:
You just need to replace the "x" with the "a".
L = X
w = X - 8
P = 52 cm
P = 2l + 2w
52 = 2(X) + 2(X - 8)
52 = 2x + 2x - 16
52 + 16 = 4x
68 = 4x
68/4 = 4x/4
17 = X.
The length of the rectangle is 17 cm.
W = X - 8
W = 17 - 8
W = 9 cm.
The width of the rectangle is 9 cm.
