Question

If A = –2x + 8 and B = 2x – 4, find an expression that equals 2 A + B
in standard form.

Answer 1

Answer: -2x+12

Explanation:

So, it says the expression equals 2A + B. That means you need to multiply the equation for A by 2 and then add the equation of B to it. The question is asking you to write it in standard form. It would look like this:

2(-2x+8) + 2x-4

-4x+16+2x-4

-2x+12
