I think it’s D because if you divide 25/20 you get 1.25 and the similar pair would be 15/12.
Actually the given equation y = x^2 represents a parabola
in the set of real numbers. A parabola is defined to be a symmetrical
open plane curve created by the intersection of a cone with a plane parallel to
its side. Since the square is on the x, therefore the parabola is
opening upwards.

Answer: A compound inequality is an equation with two or more inequalities joined together with either "and" or "or". So, the answer would be the first one.
Explanation: When two inequalities are joined with and, they are often written simply as a double inequality.
Example: x ≥ -6 and x < 3 ; x < -12 or x ≥ 8
I believe the answer is 120. I am also new with permutations and combinations :)
