Answer:
b
Step-by-step explanation:
the answer is b because you add all those together then boom
Use Heron's Formula:
s means semi-perimeter = (50 + 31 + 18) / 2 = 99 / 2 =
49.5
area = sq root [(s * (s-a) * (s-b) * (s-c)]
area = sq root [(49.5 * (s-a) * (s-b) * (s-c)]
This will NOT form a triangle. The longest side (50) is greater than the sum of the other 2 sides.

The answer is 31/35
Hope it helps!
H (-7) = (-7)^2 -5 = 49-5 = 44
