Answer:
x=3
Step-by-step explanation:
using the pythagorean theorem, c^2=a^2+b^2
5^2=x^2+4^2, x=3
It would be D. because the volume of a sphere is 4/2 x pi x radius^3.
2x^2y(y^3-5)+14(y^3-5)
(2x^2y)+14(y^3-5)
2(x^2y+7)(y^3-5)
x^2y+7 Is a factor
This is pretty simple the first one is the second option the second one is the third option the third one is the third option and the fourth one is the first option
