Yes because removing the common factor is important. There are a few steps, then you can factor by regrouping. Hope this helps.

Put the value of x = -1 to the equation of a function f(x):
Answer:
107 degrees
Step-by-step explanation:
For an inscribed quadrilateral, the opposite angles are supplementary. Thus, B+D = 180 and you can solve for x.
3x+9+2x-4 = 180
5x = 175
x = 35
Next, plug the x value into angle A.
2(35) + 3 = 73
Angle C is the supplement of this which is 180-73 = 107
Collinear Points: points that lie on the same line. Coplanar Points: points that lie in the same plane. Opposite Rays: 2 rays that lie on the same line, with a common endpoint and no other points in common.
