A.
–30x – 6
B.
6x – 12
C.
–24x – 18
D.
5x – 12

Answer 1

i believe the answer is A

Answer 2

Multiply the coefficients to the terms in parentheses:


`-6(5x + 1) = (-6 * 5x) + (-6 * 1) = -30x - 6`


`3(2x - 4) = (3 * 2x) + (3 * -4) = 6x - 12`


`(-30x - 6) + (6x - 12)`

Combine like terms:


`-30x + 6x = -24x`


`-6 + -12 = -18`


`-24x - 18`

The answer is C. -24x - 18.
