    4x + 14

    Step-by-step explanation:

    From the question,

    L = (x + 8)

    W = (x - 1)

    Perimeter of a rectangle

    = 2 (L + B)

    P = 2 (x+8 + x-1)

    Using distributive property

    We have

    2xx + 2x8 + 2xx - 2x1

    2x + 16 + 2x - 2

    2x + 2x + 16 - 2

    4x + 14
