X(6x2 – 4x –2) equals which of the following expressions? a. 6x3 – 4x – 2 b. 6x3 – 4x2 – 2x c. 6x3 – 4x2 – 2 d. 7x3 – 5x2 – 3x

B

Step-by-step explanation:

You just distribute the x. Your final answer would be (6x^3)-(4x^2)-2x

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
