Answer:
13x-9
Step-by-step explanation:
9×(x - 1)
9x - 9 +4x
collect like terms, 9x+4x=13x
The answer is 2520 degrees
X=1 is the answer to your question
Essentially, we are trying to find the missing constant term of 
(remember that we are subtracting 
due to the negative sign in front of the second term). Let's expand this to see what we can work with:
Now, we know the second term is 
, so let's set the second term in the polynomial we just found equal to :
- Divide both sides of the equation by
- Divide both sides of the equation by 2
We have found . We know the missing constant term is 
, according to the polynomial we found earlier. Thus, the missing term is:
The missing constant term is 36.
Answer: x= -2/5 or x= -0.4
combine like terms on left side and get -11+2x. then combine terms on right side and get -13-3x. add the 11 to the right side and get 2x= -2-3x
then add over the 3x and get 5x=-2
and finally divide the -2 from 5x and get -2/5
