Answer:
31.68d + 8.8
Step-by-step explanation:
We have to simplify the expression but with one dillemma. The number 8.8 is outside the parenthesis of 3.6d + 1 and 3.6d + 1 aren't combinable because they aren't like terms.
When we have a problem like 8.8 being out of the parenthesis, we need to distribute 8.8 to both numbers in the parenthesis, or in other terms multiplying.
(8.8 * 3.6d + 1 * 8.8)
31.68d + 8.8
