Express the area of a rectangle of x+6 and x+2

x²+8x+12, do the distributive property

Step-by-step explanation:

x+6 times x+2 is equal to x(x+2) and 6(x+2) , that will leave you with x²+2x and 6x+12. Add these together to get x²+8x+12

then, the surface area of the sphere shown in the image is: 256π sq. units!

step-by-step explanation:

the lateral surface area of a sphere is 2πrh where h=2r.

then:

surface area = 4πr^2.

in this case, r=8 units ⇒ surface area = 4π(8 units)^2. = 256π sq. units!

then, the surface area of the sphere shown in the image is: 256π sq. units!
