A) 30^2 = x(2x + 70)
B) 30x^2 = 2x + 70
C) 302 = 70x * w mph
D) 30 + 30 = 70 + x * 2 mph
E) 30 * 2 = 70x^2
F) 100 = x^2 + x

    The area of the square = 30^2  ft^2

    area of the rectangle = x * (2x + 70) ft^2 (where x = the width)  and these areas are equal. Therefore:-

    30^2 = x(2x + 70)

    Its A
