f (x) = log ( 1+x / 1-x ) ---- 1
f ( 2x / 1+x2 ) = ???
to find this ----- in equation 1 replace "x" by ( 2x / 1+x2 )
then
f ( 2x / 1+x2 ) = log ( 1 + x2 + 2x / 1 + x2 - 2x )
f ( 2x / 1+x2 ) = log ( 1+x / 1-x ) 2
f ( 2x / 1+x2 ) = 2 log ( 1+x / 1-x )
f ( 2x / 1+x2 ) = 2 f(x)

Answer:
The population of the United States is 387.87 times larger than the population of Columbus, Ohio.
Step-by-step explanation:
8.25 times 10^5 = 825,000
3.2 times 10^8 = 320,000,000
320,000,000 divided by 825,000 = 387.87
40 individual hotdogs and 40 individual hot dog buns
4 hotdog packages and 5 hot dog bun packages
multiples of 10: 10, 20, 30, 40, 50, 60, 70, 80
multiples of 8: 8, 16, 24, 32, 40, 48, 56, 64, 72, 80
Least common multiple (LCM) is 40
10*4=40
8*5=40
