Given that AE - CE, BE = 6 - 2x, and CE = 10 – 4x, find the value of x for which
ABCD must be a parallelogram.

answer: the answer is e

step-by-step explanation:

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)

answer: 12x^2+6x

step-by-step explanation:

6x does not equal 24x. hope it works!
