If angle 1 and angle 2 form a linear pair. If measure of angle 1 = (5x+9)° and measure of angle 2 = (3x+11)°, fine the measure of each angle.

Which of the following expressions is equal to 2x^2+8

List the sides of δrst in in ascending order (shortest to longest) if: m∠r =x+28°, m∠s = 2x+16°, and m∠t = x+12°

50 will mark show all use the linear combination method to solve the system of equations. explain each step of your solution. if steps are not explained, you will not receive credit for that step. 2x+9y= -26 -3x-7y=13
