Exercise 2 Page 113

Distribute the factor to the terms inside the parentheses.

27 - 9d

Practice makes perfect
We want to simplify the given expression. To do it, we will use the Distributive Property. We will distribute - 4.5 to the terms inside the parentheses.
- 4.5 (- 6+2d)
- 4.5 (- 6)+(- 4.5)2d
4.5 * 6 +(- 4.5)2d
4.5 * 6 - 4.5 * 2d
27 - 9d
Since 27 and 9d are not like terms, the expression cannot be simplified further.
