There are 18 possibilities and only one of them is a thin crust pepperoni with tea so it is 1/18
18(y-5)^2=x+3
do the algebra to make it into =x form
x=18y^2-180y+447
then you take the form of the focus, you can do the math
(-215/72, 5)
8:15 or 8 to 15 would be the ratio because you compare 8 quarters to 15 coins.
The answer would be 314.16 square cm
Hope this helps! :)
Lets count...
3a...thats 1 term
3ab...thats 2
7b....thats 3
-2c....movin on up to 4
-4d....and we end at 5
so this expression has 5 terms since none of the terms can be combined :)
