SORRY I DID NOT UNDERSTAND
You surveyed 30 students to see how many CDs they owned.
The number of students who owned 5 - 8 CDs was:
= 15
The number of students who owned 9 - 12 CDs was:
= 10
The number of students who owned 13 - 16 CDs was:
= 5
The number of students who owned 17 - 20 CDs was:
= 0
The total number of students surveyed is the sum of the above:
= 15 + 10 + 5 + 0
= 30 students
30 students were surveyed for this study.

D, you have to factor 3 out of 6x squared
(25-y) ^2-y^2=25
y=12
x=25-12
x=13
(13,12)
The answer is -21.4
Hope that answers your question ;)
