[AI-generated answer — Bot GPT 3.5]

To simplify the expression 9(k+13)+10(12k−1), we can first distribute the 9 and 10 to the terms inside the parentheses:

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

Multiplying the terms:

= 9k + 117 + 120k -10

Combining like terms:

= 9k + 120k + 117 - 10

= 129k + 107

So, 9(k+13)+10(12k−1) simplifies to 129k + 107.
