1. So in your formula replace the r with (2x+3)
that is...
S = 4(PI)(2x+3)(2x +3)
Now use the distributive property to simplify...
2. total area - sky light = area remaining
(10x+9)(7x+7) - (x+5)(3x+3) = remaining area.
Use the distributive property to expand both sets of brackets then collect like terms.
PLEASE HELP!!!
1. A sphere has a radius of 2x+3. Which polynomial in standard form best describes the total surface area of the sphere? Use the formula S=4πr^2 for the surface area of a sphere.
2. 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?
