Answer:
not sure about 1
for number 2 it is 5 over 4 . for y, 5 10 15 20 is a multiple of 5 so the change is 5. for x, 4 8 12 16 is a multiple of 4 so the change is 4.

Step-by-step explanation:
Pythagorean Theorem: 
In this case, a = 9, b = a, and c = 15.
The, we subtract 81 from both sides getting:
,
Then,
Total number of parts:
2+3=5.
Each part is:
20 cookies/ 5 parts= 4 cookies/part.
Number of chocolate cookies is:
4 cookies/part* 2 parts= 8 cookies.
Number of sugar cookies is:
4 cookies/part* 3 parts= 12 cookies.
There are 8 chocolate cookies and 12 sugar cookies~
