Iam hoping someone could kindly show the step by step instruction to solve this equation. i have tried to solve it many times but it is still not clear, could someone show the steps 2(8r^2+r)-4r

30r

Step-by-step explanation:

2(8r2+r)-4r

2(17r)-4r

34r-4r

30r

16r^2-2r

Step-by-step explanation:

2(8r^2+r)-4r

(16r^2 +2r)-4r               Distribute the 2

16r^2+(2r-4r)                Regroup like terms

16r^2-2r

Hope this helps!

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

d.) yes, because the volume of the cone is greater than the volume of the sphere
