Find the difference (x^3-7x+4x^2--9x+4) = ? x^3+? x^2+? x+?

=x3+2x2+2x−6

Step-by-step explanation:

x3−7x+4x2−2+−1(2x2−9x+4)

x3+−7x+4x2+−2+−1(2x2)+−1(−9x)+(−1)(4)

x3+−7x+4x2+−2+−2x2+9x+−4

x3+−7x+4x2+−2+−2x2+9x+−4

(x3)+(4x2+−2x2)+(−7x+9x)+(−2+−4)

x3+2x2+2x+−6

18.8 cubic inches.

step-by-step explanation:

volume of a cone = πr²h

r = 1.5 inches

h = 8 inches

pi = 3.14

volume of our cone = × 3.14 × 1.5² × 8 = 18.84 square inches

or equals to 18.8 square inches rounded up to nearest tenth.

ik how do do this just give me a few minutes and i will give it to
