Question

add 9(k+13)+10(12k−1)

Answer 1

To simplify the expression, you need to distribute the numbers outside the parentheses to the terms inside the parentheses and then combine like terms.

9(k + 13) + 10(12k - 1)

First, distribute 9 to the terms inside the first parentheses:

9k + 9(13) + 10(12k - 1)

Next, distribute 10 to the terms inside the second parentheses:

9k + 9(13) + 10(12k) + 10(-1)

Simplify within each set of parentheses:

9k + 117 + 120k - 10

Now, combine like terms:

(9k + 120k) + (117 - 10)

129k + 107

The simplified expression is 129k + 107.
