I believe the answer is 5 2/5 if that helps!
I just turned 3 3/5 into a mixed number. Then dived that by 2/5 and got 5 4/10 which simplifys to 5 2/5!

Answer:
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
