5(2n+7)
So, you have to multiply 5 with all the numbers that are inside the parentheses. First, 5•2n is 10n and than 5•7 is 37. And the final answer is 10n+35. That’s the final answer. You don’t need to add 10n and 35 because 10 have a (n) a letter and 35 doesn’t, it’s different. :) hope you understand.
