Final answer:
To find h(g(n+1)), substitute g(n+1) into the expression for h(n) by using the given formulas for g(n) and h(n). Simplify the expression if necessary.
Step-by-step explanation:
To find h(g(n+1)), we need to substitute g(n+1) into the expression for h(n). First, find the value of g(n+1) by substituting n+1 into g(n). So, g(n+1) = (n+1)^2 + 5(n+1). Then, substitute this expression into h(n) to get: h(g(n+1)) = 3(g(n+1)) + 3. Simplify the expression further if needed.
