The major advantage of exponential notation is that it simplifies a number into a more readable form, so we don't have to count all the zeros every time we look at it / calculate it. It helps us to identify big numbers as small decimals which we are more familiar with.

Hope this helps! :)
Hello,
Let's w the width , l the length, p the perimeter.
w=l-5
p=2(l+w)=2(l+l-5)=4l-10
4l-10=122
==>4l=122+10
==>4l=132
==>l=132/4
==>l=33
So w=33-5=28
Proof:
2*(33+28)=2*61=122
The answer would be 12 : 5
This is because it is cheese : sausage.
There are 12 cheese and 5 sausage. (add the rest and of the pizzas, and subtract from 25, which means there are 5)
So you get 12 : 5
This set of points is a function because each input has exactly one outout.
