Answer:
22
Step-by-step explanation:

For this problem, I have to know the amount of distance to get to Room 117. If I do, I can give an exact answer to this problem. Through dimensional analysis, you have divide distance with speed to determine the time:
Time = Distance/Speed
Time = d/4
As long as you know the distance, when you substitute it to d in the equation, you can already answer the time.
It would be 3 cubic feet……………..
The answer is 1/4 but I didn't get what dependent or independent
The zeros are -2, 1, and 2
If you graph it you can find out the rest
