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.
Answer:
(2, 3) lies on the line y = 5 - x.
Step-by-step explanation:
Were there only two possible answer choices?
We can determine whether or not a given point, such as (2, 3), is contained in a function such as y = x - 1, by substituting the given coordinates 2 and 3 for x and y respectively; is the resulting equation true or false?
Check out (2, 3) and y = x - 1: 3 = 2 - 1, or 3 = 1. False. (2, 3) does not lie on the line y = x - 1. Does (2, 3) lie on the line y = 5 - x? Is 3 = 5 - 2 true? Yes. So (2, 3) lies on the line y = 5 - x.
Check out (2, 3) and y = 7 - 2x. Is 3 = 7 - 2(1) true? No, it is not true.

it is the same thing, BUT it it always y's over x's and always in the same order of 1 and 2:
