Hi there! The answer is A.
(2x² + 3x - 10) - (x² - x + 111)
Let's solve this problem step by step!
First work out the parenthesis. Because we multiply by negative 1, we mustn't forget to change the symbols in front of the factors.
2x² + 3x - 10 - x² + x - 111
Now rearrange our expression, in order to collect the terms later.
2x² - x² + x + 3x - 10 - 111
And finally collect the terms.
x² + 4x -121
The answer is A.

Answer:
x=20 and y=100
Step-by-step explanation:
Using vertical angles, angle 1 and 3 equal each other. Therefore, x=80/4. Then, by using the sum of angle 1 and 3, 160, and using vertical angles again, we can find angle 2, which is (360-160)/2.
IMproper fraction is what you need to covert it 2 cuz u multiply then add and u'll get it
