9. 18x

10. x - 9

11. 12x

12.

13. 2(x - 11)

14.

Step-by-step explanation:

9. Remember that product means multiply, so 18 * x is the equation. Or 18x.

10. If the price is represented by x, and it decreases by 9, then we can represent that by x - 9.

11. Times means multiply. We can use x for the number of hours, so 12 * x or 12x works in this situation.

12. Sum means to add so we would add c squared and 14 to get c^2 + 14.

13. A number decreased by 11 is represented by x - 11, and all of that is multiplied by 2.

14. A number divided by 4 is represented by the x/4. All that is multiplied by 5.

I hope this helps!!

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

1/2*qr*rs
