    B) 2x + 18 = 100

    Step-by-step explanation:

    Given: Perimeter = 100 feet and width = 9 ft

    We know that the perimeter of a rectangle = 2 (length + width)

    Let "x" be the length of the rectangle.

    Plugging in the given values in the above formula, we get

    100 = 2 (x + 9)

    On the right hand side, we can use the distributive property a (b + c) = ab + ac

    and expand.

    100 = 2x + 2*9

    100 = 2x + 18

    This is same as 2x + 18 = 100

    Therefore, the answer is B) 2x + 18 = 100
