x2−x−42x−8


x2−x−4x−4

Answer 1

X-9x-4+×2-x+5×-4 can be simplified by combining like terms.

Starting with the x terms:
X - 9x - x = -9x

Next, the constants:
-4 + 5(-4) = -4 - 20 = -24

Putting it all together:
X-9x-4+×2-x+5×-4 = -8x - 24

Therefore, none of the expressions listed is equal to X-9x-4+×2-x+5×-4.
