Select the correct answer from each drop-down menu. The sum of the polynomials 6x3 + 8x2 - 2x + 4 and 10x3 + x2 + 11x +9 is
of
Adding 3 this sum gives a sum

1st :   16x^3 + 9x^2 + 13x + 13

2nd : 16x^3 + 9x^2 + 13x + 16

Step-by-step explanation:

  6x^3 + 8x^2 -  2x + 4

+10x^3 +   x^2 + 11x + 9

 16x^3 + 9x^2 + 13x + 13

                                 +  3

 16x^3 + 9x^2 + 13x + 16

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
