Answer:
The area of the trapezoid should be:
A = (a + b)/2 · h = (4 + 8)/2 · 4 = 24
So the area of the trapezoid is 24 square units.
The solution to the system is where the lines intercept. If you look at the graph, you see that the lines intercept at (1,2). So, the answer would be C.

Answer:
0---22.5 and 21---36
Step-by-step explanation:
you will always have 21 free CDs so you can put a closed circle on 21 then you can have a max of 15 CDs (180/12) soo put another closed circle on 36
now time for tapes, which is easier, the minimum is 0 and the max is 22.5. Now put closed circles on each and you're done. Except that .5 might get you in trouble, use your own discretion on rather to leave it on the .5 or round. I don't know what your teacher is looking for so I will let you decide.
