Would have to be C due to all the other numbers not adding up to be a right angle
2x²(a-b) + x(b-a) + 6(b-a) = 2x²(a-b) - x(a-b) - 6(a-b) = (a-b)(2x²- x - 6)=
=(a-b)(2x+3)(x-2)
6x²(a-b) + x(a-b) + 12(b-a) = 6x²(a-b) + x(a-b) - 12(a-b) =(a-b)(6x²+x - 12)=
=(a-b)(3x - 4)(2x + 3)
I think I know what it forms - a cone!!
I'm guessing that the angles at the end are 10 degrees so that would make angle CAB equal 5 degrees.
Line AB would be the radius of the "upper cone".
Line BC is 12/2 or 6
tangent (A) = BC / AB
tangent (5) = 6 / AB
AB = 6 / tan(5)
AB = 6 / 0.087489
AB =

68.58 which is the radius of the "upper cone".</span></span></span>
Cone Volume = (PI * radius^2 * height) / 3
Cone Volume = (PI * 68.58 * 68.58 * 6) / 3
Cone Volume =

29,551
That is just the "upper cone volume. So, we multiply </span></span></span><span><span>

29,551 * 2
and get 59,102 which is the volume of the entire solid.

Answer:
x=4, x=-14
Step-by-step explanation:
With a radical
Hope it helped :)
Use proportion
106 % = x + 8,800 where x is the selling price
100 % = x
so 106 / 100 = 1.06 = (x + 8800) / x
1.06x = x + 8800
0.06x = 8800
x = 8800 / 0.06 = $146,666.67
