Can someone help please

2x^2 + 4

Step-by-step explanation:

f(g(x)) just means to first solved g(x) and put the solution into f(x).

Therefore, it becomes f(x)=(10x^2+5)/5 + 3, and you can simplify that into

2x^2 + 4.

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
