Simplify the following expression by combining like terms.
9 - 12x + 2x - 5

4-10x

Step-by-step explanation:

like terms: 9 and -5, -12x and 2x

9-5= 4

-12x+2x= -10x

Put them together:

4-10x

where are the options?

step-by-step explanation:

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
