Step-by-step explanation:
6x - 3x^2 + 2x^2 -2x = 5x^2 + 15x
4x -x^2 = 5x^2 + 15x
-11x - 6x^2 = 0
-6x^2 - 11x = 0
use the quadratic formula
(-b±√(b²-4ac))/(2a)
angle EPF = angle DPG
=> 4x + 48deg = 7x
=> 3x = 48 deg
=> x = 16
=> angle EPF = 4(16) +48 = 112deg
The answer is B because there are more white socks than blue or black.

Y=-x^2-2x+3 a=-1, b=-2, c=3
To find the x coordinate of the vertex, we use this formula: x=b/2a
So plug everything in and you'll get x=1.
Now plug that in the original equation to find the y coordinate.
