Use set notation and spherical coordinates as in the equation f = {(rho, θ, ϕ) | θ1 < θ < θ2, ϕ1 < ϕ < ϕ2, g(θ, ϕ) < rho < h(θ, ϕ)} to describe each region. the region in the first octant that is below the cone z = 3x2 + 3y2 and inside the cylinder x2 + y2 = 9.

Question: what is the value of x 4x-2= (-7) +5x. it would be greatly appreciated if someone could actually explain to me step by step
