Answer:

14.652c - 21.22c

Explanation:

We need to expand the parentheses by using distribution. Distribution is essentially where you take the sum of the product of the outside term and each of the inside terms.

Here, the outside term is -1.01 and the inside terms are 22b and -5.2c. So, we have:

-1.01 * (22b - 5.2c) = -1.01 * 22b + (-1.01) * (-5.2c) = -22.22b + 5.252c

Now add this back to the previous equation:

9.4c − 1.01 * (22b − 5.2c) + b

9.4c - 22.22b + 5.252c + b = 14.652c - 21.22c
