What is f(x)= 13,500 (times) 0.89^4?

If y varies directly as x2 and y=6 when x=6, find the constant of variation.

[15 points]find the least common multiple of the expressions: 1. 3x^2, 6x - 18 2. 5x, 5x(x +2) 3. x^2 - 9, x + 3 4. x^2 - 3x - 10, x + 2 explain if possible

Are the corresponding angles congruent? explain why or why not.
