Simplify completely 12 times x to the third power minus 4 times x to the 2nd power plus 8 times x all over negative 2 times x
lawyer [7]
(12x^3-4x^2+8x)/(-2x)  The greatest common factor of the numerator and denominator is -2x so upon division by GCF of both numerator and denominator you have:

-6x^2+2x-4  and we can now also factor out -2

-2(3x^2-x+2)

Dmitry_Shevchenko [17]

The measure of angle one is equal to 60.75 degrees because angle 1 and 60.75 angle are corresponding, so they are congruent.

The measure of angle two is 119.25 degrees because it is supplementary to angle 1.
