Answer: 51) 25
Explanation:
51) start by finding h(81). Simply plug in 81 for x in the h(x) function. This gives you the square root of 81 + 5. Square foot of 81 is 9 and 9+5=14. Now solve g(-2) by plugging in -2 into the g(x) function. So you have (-2)^2 -15=4-15=-11. Now that you have your answers for h(81) and g(-2) solve the given problem: h(81)-g(-2). Remember h(81)=14 and g(-2)=-11. So 14-(-11)=25.
