Question

Which expression is equivalent to -3(2x - 8) + 4x?

A
B
C
D
-2x-8
-2x + 24
-10x8
-10x + 24

Answer 1

We distribute -3 to 2x and -8, and then we calculate the two multiplications.

We calculate -6x + 4x = -x(6 - 4) = -2x

`\bf - 3(2x - 8) + 4x = \\ \\ \bf = - 3 \cdot 2x - 3 \cdot ( - 8) + 4x = \\ \\ \bf = - 6x + 24 + 4x = \\ \\ \bf = - 6x + 4x + 24 = \\ \\ \bf = - 2x + 24`

The answer is B -2x + 24

Hope that helps! Have a nice day! :)
