Find two numbers that multiply to -30 (last term) and add to 7 (middle coefficient)
The two numbers are 10 and -3
10 times -3 = -30
10 plus -3 = 7
Using those two values gets us the two factors (y+10) and (y-3)
Therefore, y^2+7y-30 factors to (y+10)(y-3)
The equation y^2+7y-30 = (y+10)(y-3) is true for all values of y.
5814/27 = 215.33
215 x 27 = 5805
5814-5805 = 9
Answer is B 215 sections with 9 feet left over
For this case we have to:
d: Let the variable representing the number of miles traveled per day
Then, the cost will be given by the following equation:

If we have the cost
, then the number of miles traveled is:

Thus, the number of miles traveled is 60.
Answer:

For a
, the number of miles traveled is 60
