the sum of three angles of a triangle adds up to 180 degrees. In this problem, you are given two angles.
x+(2x+15)+the measure of angle Q should equal 180.
Since everything is addition, the parenthesis can be removed.
x+2x+15+Q=180. This can then be simplified to 2x+15+Q=180. Subtract 15 from both sides to get 2x+Q=165. Divide both sides by two to get the x by itself. x+Q=82.5.
Unfortunately I don't really know what to do from here, but I hope it helped at least a little.

x>1 (the first one)
Step-by-step explanation:
Answer:
The complete factorization is (x^2 + 1)(x + 2)
Step-by-step explanation:
In order to find this, we start by splitting the 4 term polynomial into two, two-term polynomials. Then we pull out the greatest common factor of each.
x^3 + 2x^2 = x^2(x + 2)
x + 2 = 1(x + 2)
Since the remaining parentheses are identical, we use that and the two outside to factor.
