Question

Simplify the expression with distribution: 8r - 2(7r + 9).

a: -6r - 18
b: -46r - 18
c: -6r + 18
d: 46r - 18

Answer 1

To simplify the expression 8r - 2(7r + 9), distribute the -2 to both terms inside the parentheses, then combine like terms to get -6r - 18.

Step-by-step explanation:

To simplify the expression 8r - 2(7r + 9), we need to distribute the -2 to both terms inside the parentheses. This means that we multiply -2 by both 7r and 9.

8r - 2(7r + 9) = 8r - 14r - 18

Next, we combine like terms by subtracting 14r from 8r to get -6r. So, the simplified expression is -6r - 18.
