You are welcome!
This question is not very straight forward. It is considered as a challenging E Math question.
Please be reminded that step-by-step working is expected if you want to score full marks (including all method marks) for it.

12 m/s^2 and m/s have different units. Cannot do conversion directly.
Maybe you can provide more information in the question?

Since the equation has EVEN power index, therefore, it is always positive.
In order to have the sum of (x+4)^50 + (y-5)^100 = 0,
(x+4)^50 = 0 and (y-5)^100 = 0
x = -4 and y = 5
Therefore x + y = 1.
