    Answer:

    P = 4(2x + 5)

    P = (2x + 5)+(2x + 5)+(2x + 5)+(2x + 5)

    Step-by-step explanation:

    Given that:

    Perimeter of square = 4 * s

    Where s = side length

    If perimeter, P = 8x + 20

    Then,

    4s = 8x + 20

    Divide both sides by 4

    4s / 4 = (8x + 20) / 4

    s = 2x + 5

    P = 4s

    P = 4(2x + 5)

    Or

    P = 2x + 5 in 4 places

    P = (2x + 5)+(2x + 5)+(2x + 5)+(2x + 5)
