Synthetic division (12x^4+5x^3+3x^2-5)/(x+1)

Since you have exponents this is what you end up getting.

I only used the calculator for the multiplying. (Also I used * for multiplying)

(12x^4+5x^3+3x^2-5)/(x+1)

(12x*x*x*x+5x*x*x+3x*x-5)/(x+1)

(12+5+3-5)/(x+1)

(15)/(x+1)

You divide.

You get 15.

Now you add up the x's.

15x^9 plus another x because of the one in the other parentheses.

15x^10

step-by-step explanation:

just plug in each number for x and see which ones work and don't

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
