Which is the simplified form of the expression? question 10 options: 9n – 2 9n + 2 15n – 2 15n – 8

Combine -15 + 2n first, then you get -13 n.

Then work from -13n to subtracting -9n, that is -4n. Now all you have left is -4n = 8. Divide both sides by -4n/-4 8/-4. The answer is n = -2.

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
