If 2x^2-21x+27=(2x-3)(x-9), which equation(s) should be solved to find the roots of 2x^2-21x+27=0

One of the same side angles of two parallel lines is 20° smaller than the other one. find the measures of these two angles.

Which of the following expressions cannot be simplified to x – 2?

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. 2 + 9 = −26 −3 − 7 = 13
