If f(x)=5x+12, what if f(2)?

  22

Step-by-step explanation:

Put 2 where x is and do the arithmetic.

  f(x) = 5x +12

  f(2) = 5(2) +12 = 10 +12

  f(2) = 22

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

a=24; b=12

step-by-step explanation:

a/b=2: 1

a=2b

36/(1+2)=12

b=12

a=24
