The area of a square is (x² + 8x + 16) cm?. Find the length of its side. (A) (x - 8) cm
(B) (x-4) cm (C) (x + 4) cm (D) (x + 2) cm

(C) (x +4)

Step-by-step explanation:

(x² + 8x + 16)  = x² + 4x + 4x + 16

x² + 4x + 4x + 16 = x² + 4x + 4x + 4²

x² + 4x + 4x + 4² = (x + 4)(x + 4)

*You can also plug in a value for x to check.
