Question

HELP IM REALLY BAD AT MATH! The area of a square is calculated as 4x² - 16x+16 square units. What is the length of one side of the square?

A. 2x-4
B. 4x-2
C. 2x+4
D. 4x+2

Answer 1

A. 2x-4

Explanation:

2x-4 since when you factor this expression, you get (2x-4)^2. a square has equal sides and is calculated by side length squared, so simply take the square root of the known area (2x-4)^2 and you get 2x-4.
