The value of the coefficient B is 9.
2(x+By)(x-2y)
=2(x^2 -2xy +Bxy -2By^2)
=2x^2 -4xy + 2Bxy - 4By^2
The original form is 2x^2 + 14xy - 36y^2
-36y^2 = -4By^2
B= 9
-4xy +2Bxy= 14xy
xy(-4 +2B)= 14xy
-4 + 2B = 14
2B = 18
B=9

The answer is 128 pi in^3. You have to multiply 4x4, then multiply that by 8 to get 128.
You will need to add 8 to the other side of the equation to get t = -3 + 8
A) y = 40x + 45. B) set x equal to 3 and solve for y. C) set 265 for y and solve for x.
