Question

What is the answer I’ve been at this for a while?

Answer 1

12x-4

Explanation:

First you do parenthesis. 4 times x is 4x and 4 times -1 is -4.

Now you have 8x + 4x -4

Add 8x and 4x which gives you 12x - 4.

Answer 2

Answer: 12x - 4

Explanation:

You must distribute the 4 across (x-1), which would be (4x-4), since x*4=4x and -1*4=-4.

The problem with C is that the 4 didn't multiply a negative 1, it multiplied a positive 1.
