If f(x)= 2x^2 -4x and g(x) = 5 – 2x, evaluate f(x) – g(x) for x = 5

Two positive integers are 3 units apart on a number line. their product is 108. which equation can be used to solve for m, the greater integer? m(m – 3) = 108 m(m + 3) = 108 (m + 3)(m – 3) = 108 (m – 12)(m – 9) = 108

Two angles are complementary. the large angle is 36 more than the smaller angle. what is the measure of the large angle?
