4. The Distributive Property
Continue to next subchapter

Exercise 4 Page 222

Recall the Distributive Property.

56-28d

Practice makes perfect
We want to simplify the given expression. To do it, we will use the Distributive Property. We will distribute 7 to the terms inside the parentheses.
7(2+6-4d)
7(2)+7(6)-7(4d)
14+42-28d
56-28d
Since 56 and 28d are not like terms, the expression cannot be simplified further.
