Which of the following expressions results in 0 when evaluated at x = 4?
A.
(x - 10)(x-4)
B
4X{X-6)
C. (x + 6Xx - 2)
D.
(x + 4)(x - 10)

A) = 0

Step-by-step explanation:

(4-10) x (4-4)

-6 x 0 = 0

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get

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
