Any number bigger than 3
4,5,6,7 are 4 numbers
Multiply everything in the second parenthesis by x.
-3x^3 + 3x^2 + x
Multiply everything in the second parenthesis by 2.
-6x^2 + 6x + 2
Combine these two equations together.
-3x^3 + 3x^2 + x - 6x^2 + 6x + 2
Combine like terms.
-3x^3 - 3x^2 + 7x + 2
Hope this helps!

The answer is 200 points. Because when you add this 200 to her first 200 points, you will get her final points which is 400 points. Hope I was able to help.
A figure formed by 3 segments connecting 3 non-colinear points
6y + 12 = 3y - 3
Subtract 3y on both sides
3y + 12 = -3
Subtract 12 on both sides
3y = -15
Divide by 3 on both sides
y = -5
