Plz i need . idk the answer , i will mark brainiest! combine like terms. like terms 1/2x + 1/8x a. 1/8x b. 3/8x c. -1/8x d. -1/16x

5/8x

Step-by-step explanation:

When combining like terms in this expression, you are essentially adding 1/2 and 1/8. To do this make sure both fractions have common denominators.

1/2 * (4/4) = 4/8

Now you can add them together.

4/8 + 1/8 = 5/8

5/8x is your answer.

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
