Question

Evaluate the expression at b=−2 and simplify your answer: 4(b−2)+2(b−4). What is the correct result of this expression when b=−2?

Answer 1

When b=-2, the expression 4(b-2)+2(b-4) simplifies to -28.

Step-by-step explanation:

We are asked to evaluate the expression 4(b-2)+2(b-4) for b=-2 and simplify the result. Let's substitute b with -2 and simplify step by step:

• 4(-2-2) + 2(-2-4)
• 4(-4) + 2(-6)
• -16 - 12
• -28

The correct result of the expression when b=-2 is -28.
