Question

A square has a perimeter of 12x + 40 units. Which expression represents

the side length of the square in units? *
X + 4
O x + 40
O 3x + 10
3x + 43

Answer 1

ANSWER: 3x + 10
EXPLANATION: Since there are four sides you would divide 12x and 40 by 4

Answer 2

3x+10

Explanation:

Since the perimeter of a square is 4 times the side length, to find the side length given the perimeter, just divide by 4:

(12x+40)/4 = 3x+10

Therefore, the answer is 3x+10
