7. The Distributive Property
Continue to next subchapter

Exercise 78 Page 51

Recall the Distributive Property. Remember, only like terms can be combined.

- 12cd-15

Practice makes perfect
Using the Distributive Property, multiply each term inside the parentheses by 3.
3(- 4cd-5)
3(- 4cd)+3(- 5)
Now that we have rewritten the expression, we can simplify.
3(- 4cd)+3(- 5)
- 3(4cd)-3(5)
- 12cd-15
Since - 12cd and 15 are not like terms, the expression cannot be simplified any further.
