(f○g)(x)=f(g(x))
(f○g)(x)=6(4x+1)
(f○g)(x)=24x+6
Ratio is a division in its simplest form.
To get the ratio of length to width, divide the two then simplify.
In this case, convert the length and width into decimals.
length = 7 1/2 = 7.5
width 4 3/4 = 4.75
ratio of length to width is;
7.5/4.75 = 750/475
This can now be written as;
750 : 475
Dividing both sides by 25;
= 750/25: 475/25
= 30 : 19
It's c.
for example:
2*2 +1 = 5
2*4 +1 =9
you can keep going ....
If you add up all the numbers on a 1-10 ten-sided dice, you get 55. The sum of all sides on a 20-sided dice is 210.
