Answer:
2x^2-12x-54
Step-by-step explanation:
First 2x times x along with 2x times -9
Second 6 times x along with 6 times -9
2x^2-18x+6x-54
=2x^2-12x-54
Answer:
7 degrees
Step-by-step explanation:

The main thing you are doing is adding and subtracting
Answer:
6 and 7
Step-by-step explanation:
x + y = 13
xy = 42
I just listed the two equations out and the answer just popped out. The trick to this is just thinking about two numbers that obviously both below 13 that add up to it. 6 and 7 is the solution.
