Answer:
Step-by-step explanation:
By the definition of an angle bisector, we have that 
.
We can add 
to both sides to get 
.
We can then subtract 
from both sides to get 
.
We can finally divide both sides by 
to get 
Answer:
2x^2 +11
Step-by-step explanation:
f(x) = 3x^2 + 2 and g(x) = x^2 – 9
(f – g)(x) = 3x^2 + 2 -( x^2 – 9)
Distribute the minus sign
3x^2 + 2 - x^2 + 9
Combine like terms
2x^2 +11
It is a whole number, and is positive
We have a pair of vertical angles here. So they would equal each other.
3x+50=6x-10
Subtract 3x to 6x:
50=3x-10
Add 10 to 50:
60=3x
Divide 3 to both sides:
x=30
