Which expressions are equivalent to y ⋅ 2 1/2 PLEASE HELPS :(... A) 2y + 1/2

B) 2y + 1/2y

C) y (3 − 1/2)

D) y ⋅ 3−1/2

E) y ⋅ 3 − y ⋅ 1/2

B

Step-by-step explanation:

B

Step-by-step explanation:

B is equivalent because if some thing is multiplied by a variable the answer would have the variable at the end

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!
