Step-by-step explanation:
The given equation is
This equation belongs to a circle, which center is at (0.5, 3.5) and its radius is 4.
You can deduct its elements, becase this equation of the circle is explicit, which means the constant term represents the square power of the radius. Solving that, we have
Therefore, the radius is 4 units long.

Since they expect to put 16 songs, but actually end up putting 50% more, we can do 16 * 150 % which would equal 24 songs that they actually put on their CD.
During the editing process, they removed 75 % of the songs they put on their CD. Since they put 24 songs on their CD, we can do:
24 * 25 % (because this would equal the songs left after the editing process, and not the actual number of songs removed, which is 75 %) which would equal 6 songs.
There would be 6 songs left on their Final CD.
-7 to the 3rd power is -343...
Hope this helps!
