If the sizes of interior angles of a pentagon are 2x0, 3x0, 4x0, 5x0
and 6x0, find the largest interior angle of the pentagon.

In the figure below, m∠r is 60°, and m∠t is 120°. what is m∠q? a. 60° b. 30° c. 120° d. 54

Solve this system of equations: y=x2-3x + 12 y=-2x+14 4. substitute the values of x, -1 and 2, into either origina equation to solve for the values of y. what are the solutions of the system of equations?

Factor these polynomials and explain how 1. 12x - 3x^2 2. 20 - 240x^2
