Factor completely 2x^2 + 9x + 4. a. (2x + 2)(x + 2) b. (2x + 1)(x + 4) c. (2x + 4)(x + 1) d. (2x + 2)(x + 4)

2x^2 + 9x + 4 = (2x + 1)(x + 4)

because

(2x + 1)(x + 4)

= 2x^2 + x + 8x + 4

= 2x^2 + 9x + 4

Answer is B. (2x + 1)(x + 4)

Hope it helps

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)
