. Simplify the expression. (7 – c)(–1)

Mathematics

Ganezh [65]3 years ago

For this, you use the Law of Distribution and multiply -1 by all terms in the parentheses. 7 • -1 = -7; -c • -1 = c. Then you combine them, but since c is a variable, -7 + c is the most simplified it can get. I hope this helped!
