B is between line AC. If AB = x^2– 3x, BC = 9x, and AC = 16. Solve for x.

Ialready asked this but i never got an answer. will give a high rating and perhaps brainliest. choose the linear inequality that describes the graph. the gray area represents the shaded region. y ≤ –4x – 2 y > –4x – 2 y ≥ –4x – 2 y < 4x – 2

Pls will give ! pls i dont understand

Factor the polynomial: -2x^3 - 4x^2 - 6x a. 2x(x^2 + 2x + 3) b. -2x(x^2 + 2x +3) c. -2x(-x^2 - 4x - 6) d. -2x(-x^2 - 2x - 3)
