Answer: N * (n+7) = n^2 + 7n
Explanation:
This equation would be the number, n, times n+7 because n+7 is 7 more than n. To do this, you have an equation like this:
N * (N+7). You would then do distributive property, and n*n would be n squared, and n*7 would be 7n. This would give you a combined answer of n squared + 7n, or n^2 +7n.
