Find the greatest common factor of 20 and 36

20 : 2 = 10

10 : 2 = 5

5 : 5 = 1

20 = 2 · 2 · 5

36 : 2 = 18

18 : 2 = 9

9 : 3 = 3

3 : 3 = 1

36 = 2 · 2 · 3 · 3

for this case we have the following polynomials:

where,

h (x): is the cost of producing x soccer balls

k (x): is the revenue of x soccer balls.

then the profit is given by:

substituting values we have:

rewriting we have:

answer:

an expression that represents the profit of producing soccer balls is:

a) 14x - 8
