Answer:
180 CDs
Step-by-step explanation:
So if Sam has 84 CDs, and the ratio from Sam to Alice is 7:8, we can do 84/7=12 so each number is equal to 12. Then we add up 7 and 8 and get 15, so we do 15*12 and we get 180.
35% of 60 is 21. Hope this helped!
D. The set of people with Social Security Cards and the set of Social Security numbers.
Is the scenario that exhibits a function relation.
A function is a set of ordered pairs wherein each x-element has only ONE y-element associated with it.

Das is difference of 2 perfect squares
remember
a^2-b^2=(a-b)(a+b)
so
25x^4=(5x^2)^2
16y^2=(4y^2)
(5x^2)^2-(4y)^2=(5x^2-4y)(5x+4y)
cannot be factored further
