14. A cylinder has a radius of x + 2 and a height of x + 4. Which polynomial in standard form best describes the total volume of the cylinder? Use the formula V = nr2h for the volume of a cylinder.
15. A sphere has a radius of 2x + 3. Write the polynomial in standard form that best describes the total surface area of the sphere? Use the formula S = 4tr for surface area of a sphere.
16. A carpenter is putting a skylight in a roof. If the roof measures (10x + 9) by (7x + 7) and the skylight measures (x + 5) by (3x + 3), what is the area of the remaining roof after the skylight is built?

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc

sweetheart, there isn't a cube below.

96 cm is the answer.
