The number of rows in an auditorium can be represented by the function f(x) = 80x. The number of seats in each row can be repres
rusak2 [61]

Answer:

h(x) = 80x^2 + 560x

Step-by-step explanation:

To find the function h(x), that represents the total number of seats, we just need to multiply the functions f(x) (number of rows) and g(x) (number of seats per row):

h(x) = f(x) * g(x)

h(x) = 80x * (x+7)

h(x) = 80x*x + 80x*7

h(x) = 80x^2 + 560x

So the function that represents the total number of seats is:

h(x) = 80x^2 + 560x
