6r^2 + 13rd + 6b^2 Cannot be factored. I don't think that is the equation. Are you sure you don't have a couple typos?

Math(Urgent)

Mathematics
y = 1/2 x - 2 In the 2nd column all of the points have x = +6 y = 1/2 x - 2 y = 1/2(6) - 2 y = 6/2 - 2 y = 3 - 2 y = 1 Therefore, none of the choices are correct (since none of the points have y = 1). I think you have a typo because if I use x = -6 y = 1/2 x - 2 y = 1/2(-6) - ...

Correction for above, | = integrate symbol y = x^3 y^3 = x, y = x^(1/3) Using the formula pi | (f(x))^2 - (g(x))^2 dx pi | x^(1/3)^2 - (x^3)^2 dx pi | x^(2/3) - (x^6) dx pi ( 3/5 x^(5/3) - 1/7 x^7 ) When I evaluated from 0 to 1, I got, 16/35 pi
