Answer: m = 7 or -2
Step-by-step explanation:
Quadratic Formula! 
Polynomial Form: 
So in this example a: 1 b: -5 c: -14
You get:
m = 7 or -2
Check by plugging a value back in for m

True for both.
D. 180/4=45. That’s the distance in an hour. Then multiply that by 8.
The answer to the question is 2,085,000
Looking at the graph, we know that A. 3 boxes are filled every 4 min and D. 0.75 boxes are filled per minute are the correct answers.
