Answer:
615
Step-by-step explanation:
The ratio of the given terms can be used to find the common ratio between terms:
a5/a2 = (a1·r^(5-1))/(a1·r^(2-1)) = r^3 = 768/-12 = -64
r = ∛-64 = -4
So the first term is ...
a1 = a2/r = -12/-4 = 3
And the first 5 terms of the series are ...
3 + (-12) + (48) + (-192) + 768 + ...
The sum of the first 5 terms is 615.
The discriminant is-
b^2-4ac=64-64=0
as the discriminant is 0, one solution will be -b/2a = -1/2
But still, we can't say that it has only one solution due to the nature of quadratic equations(It's tendency to have two solutions).
But we can say that both solutions are coincident.
Hence it has two solutions.

Answer: the answer is 3/2
I know this because my brain is right
The answer is B because its going 90m/s and and in 2 seconds its traveled 180 meters which if you add to 60 gives you 240
