Answer:
v = 15
Step-by-step explanation:
Sum of the angles inside a triangle add up to 180
angle 1 = 31
angle 2 = 4v+44
angle 3 = 180 - 9v
since 9v is the supplement to the angle inside the triangle then
some angle + 9v has to equal 180
which we can solve for the that angle to be 180 - 9v
therefore
180- 9v + 31+ 4v+ 44 = 180
Simplify it down by combining like terms
255 -5v = 180
subtract 255 to both sides
-5v = -75
divide by -5
v = 15
Simplifying 
we get 
Step-by-step explanation:
We need to simplify
Basically, we need to find the product of all terms.
Finding product:
Using exponent rule: 
So, simplifying we get

Easy.
2x + 3x
2x + 3x
2x ( 1 + 3x / 2x )
2x ( 1 + 1.5 )
2x ( 3 )
6x
or
2x ( 3 )
or
3x ( 2 )
That's it.
