Which expression is equivalent to (3w−8)−4(2w+3)(3w−8)−4(2w+3)?
kolezko [41]
(3w-8)-4(2w+3)(3w-8)-4(2w+3)
(3w-8)-(8w+12)(3w-8)-4(2w+3)
(3w-8)-(24w-96)-4(2w+3)
(3w-8)-(24w-96)-(8w+12)
(-21w-104)-(8w+12)
-29w-92
So the simplified form of this expression is -29w-92. When you look at the answer choices you have, pick the one that would make equal value with the simplified form of the one you gave here.
