The side of a square is (4x-2y) what is the perimeter of the square

P = 14x - 8y

Step-by-step explanation:

Since the square has 4 sides that are all of equal length the perimeter is:

P = 4*(4x - 2y) (4 times the length of the side, that is (4x - 2y))

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.
