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:
Step-by-step explanation:
L=3S
In 5 years,
L+5=2(S+5)
L+5=2S+10
L=2S+5
Substituting from above,
3S=2S+5
S=5
So then,
L=3(5)
L=15
This is simple. Coordinate form is (x,y) so you would just plug in your values.
2(5)-(1)=11
10-1 does not equal 11, so no it is not a solution.
