Select all polynomials that have by (x -3) as a factor. Choose all answers that apply:
A. A(x) = x^3-2x^2-4x+3
B. B(x) = x^3+3x^2-2x-6
C. C(x) = x^4-2x^3-27
D. D(x) = x^4-20x-21

Find the value of x for which the lines are parallel.

The width of a rectangle is 20 units. can the perimeter p of the rectangle be 64 units when its length x is 11 units? no, because p = 2x + 2(20) no, because p ≠ 2x + 2(20) yes, because p ≠ 2x + 2(20) yes, because p = 2x + 2(20)

Mackenzie needs to determine whether the rectangles are proportional. which process could she use? check all that apply.
