Your awnser is a because 192x6=1152.
This means that (x-6)(x+2) = f(x) is the equation for the parabola due to that if you plug these in, when x=6 and x=-2 then y=0. Expanding it, we get
x^2+2x-6x-12=x^2-4x-12. Since the x coordinate of the vertex is -b/2a, it's 4/2=2
Answer:

Answer:
35x-35y
Step by step explanation: I
0.5(20x-50y+36)-0.25(100x+40y-12)
10x-25y+18+25x-10y+3 -------- after we distribute 0.5&-0.25
10x+25x-25y-10y+18+3. ---------we collect the like terms to add them or substract
35x-35y+21 -----------------------------simplified form
