Answer
The answer is C. Trina is not correct because the two sides of the equation are equivalent.
Step-by-step explanation:
1. solve for x
-8(x - 4) + 2x = -4(x - 8) -2x
-8x + 32 + 2x = -4x + 32 -2x
-6x + 32 = - 6x + 32
0 = 0
This equation has infinite solutions, any rational number fits as solution for x in this equation. And as we can see both sides of it are equivalent.
Therefore, the correct answer is C. Trina is not correct because the two sides of the equation are equivalent.

Ignore the -4y term for now. Only focus on x^2+20x+100. This can be factored to (x+10)^2. Notice how expanding it out gives
(x+10)^2 = (x+10)(x+10)
(x+10)^2 = x(x+10) + 10(x+10)
(x+10)^2 = x^2+10x + 10x + 100
(x+10)^2 = x^2 + 20x + 100
So this means
x^2+20x-4y+100 = 0
turns into
(x+10)^2 - 4y = 0
after we factor
The second equation listed above implies that we have a parabola because we can solve for y to get
-4y = -(x+10)^2
y = (1/4)(x+10)^2
If you take 54 skittles and multiply that by 8 you would get 432 which would not equal 483 so she would have 51 skittles left over which would not be correct so if you divide 483 by 8 everyone would get 60 skittles
