The U and inverted U symbols, ∪ and ∩, are mathematical symbols used to denote union or intersection, respectively. For example, when a rational algebraic equation is graphed, there may be some points where the equation is undefined. Visually, we see it as breaks or discontinuities. We use the ∪ symbol to express union. For example, {-∞,2)∪(4,+∞). That means that the graph passes at all x values except x=3.
The ∩ symbol is used for intersection of two lines, for instance. When equation A and equation B are graphed, they can intersect at points (x,y). It is therefore expressed as: A∩B = (x,y).

Use Pythagorean theorem:
Leg: 12
Hypotenuse: 15
12^2 + x^2 = 15^2
144 + x^2 = 225
x^2 = 81
x = 9
Hello from MrBillDoesMath!
Answer:

Discussion:
(g-f)(5) =
g(5) - f(5) =
(2(5)+13) - (5^2-12) = => as 5^2 = 25
(10+13) - (25-12) =
23 - 13 =
