What is the volume of the sphere?

Step-by-step explanation:

Remember the equation for the sphere is...

First step:

Second step:

Third step: Don't do 27 times 3 first. Make sure to cross out the dominator of 4/3, which is 3, and the 27.

Fourth step: Change the 27 to 9.

Fifth step: Multiply 4 times 9, which is 36.

Sixth step: Final answer is

Hope this helps and stay safe during these crucial times. We'll get through this!

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice

p.s.   i'll be on vacation from friday, dec 22 to jan 2, 2019. have a great new year!

easy its decreasing
