Answer:
x = 9
Step-by-step explanation:
Create an equation:
x = some number
and = add
other number = -15
x + (-15) = -6
remove () using rule
x - 15 = -6
add +15 to both sides
x = 9
9.75 i think I’m not really sure do you have any options?
Since this is a triangle all the angles within the triangle add up to 180 degrees so....
82+(9x+2)+(7x)=180
82+2+16x=180
16x+84=180
16x=96
X=6
If we plug in X to angle(9x+2) and angle (7x) we will get 56 and 42. We can get angle 2 by subtracting 180-42 which is 138
FINAL ANSWER: 138 degrees
If you want a polynomial to have the x-intercepts of your choice, you simply have to build a polynomial by multiplying pieces like 
where 
is the x-intercept you want.
So, if you want x-intercepts 0 and 4, you have to build the polynomial
