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:

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

Answer:

1.25 x 10⁷ km

Step-by-step explanation:

Distance QR = √(3.5 x 10⁶)² + (1.2 x 10⁷)²

= √12.25 x 10¹² + 1.44 x 10¹⁴

= √10¹² (12.25 + 144)

= 10⁶ x 12.5

= 1.25 x 10⁷ km
