Answer

24 experts

Step-by-step explanation:

As shown in the diagram,we let

U=[Total number of experts who voted]

This implies that the number of experts who voted for Mr A in terms of x is

And in terms of x, the number of experts who voted for Mr B is

From the diagram, we can write the below equation,

We multiply through by the L.C.M (is that 6) to get,

just take the area of the square and then the area of the circle then subtract the circle area from the squares area

step-by-step explanation:

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
