Verified Answer :

You must distribute first, so 3(8p+7r). That will equal 24p +21r. Then you must add all the values together according to like terms, so the variables must match. So simplified it will be 22+24p+30r

The simplified expression would be 30r + 24p +22.

To solve, distribute the 3 to the numbers in the parentheses. Then, add like terms.

9r + 7 + 3(8p + 7r) + 15
9r + 7 + 24p +21r + 15
30r + 24p + 22

Hope this helps! :)
