choice C: x2 -3x -3
Step-by-step explanation:
(3x^2-7x+2)-(2x^2-4x+5)
becomes
3x^2-7x+2 -2x^2+4x-5
adding
3x^2-2x^2 -7x+4x +2-5
which is
x^2 -3x -3
Answer:

Answer:
x is 64 degrees
Step-by-step explanation:
Since the polygon is a quad we know all the angles add up to 360. So, we can do :
100 + 130 + 66 = 360 - x
296 = 360 - x
Subtract 360 on both sides
-64 = -x
Multiply by negative one on both sides and we get
64 = x
x is 64 degrees
