Answer:
It is 0
Step-by-step explanation:
The answer is the first tile on the very left
s = sqrt(227) where "sqrt" is shorthand for "square root"
To get this answer, we basically replace A with 227 and we go from
A = s^2
to
227 = s^2
So if s^2 = 227, then s = sqrt(227) after we apply the square root to both sides. Because s is some length value, it makes no sense to have it negative. Therefore we don't consider the negative version of the square root.
Your answer would be 2.6 meters per second
390 ÷ 150 = 2.6
