Ineed to know the values of x that are not in the domain of h.

x = - 7, + 7

Step-by-step explanation:

The denominator of h(x) cannot be zero as this would make h(x) undefined. Equating the denominator to zero and solving gives the values that x cannot be.

solve :

x² - 49 = 0 ⇒ (x - 7)(x + 7) = 0 ⇒ x = ± 7

The domain is valid for all x ∈ R , x ≠ - 7, + 7

81 seats

step-by-step explanation:

if you multiply 0.65 times 125 then you get 81.5 seats. well since you can't have half of a seat you have to round down and get 81 seats in the no children zones. that leave 44 seats outside of the no children zone.
