Answer:

Step-by-step explanation:

A number to an exponent is the number times itself. A number to the "n"th power would be that number times itself "n" times.
This means that the fraction above could also be expressed as;

If these parameters, "a", "b", "c", and "d" are given a value, then one can solve this equation.
Let the speed of the first train be v mph. Then the speed of the second train is:
(v + 50) mph.
Distance traveled by the first train from 3pm to 7pm = 4v miles.
The second train travels 4v miles in 2 hours (from 5pm to 7pm). Therefore the speed of the second train = (4v)/2 = 2v.
However the speed of the second train is also given by (v + 50) mph.
v + 50 = 2v
v = 50.
The speed of the first train is 50 mph and the speed of the second train is 100 mph.
Factors of the given quadratic are irrational. You could say it is
Prime

roots are 3.5±√4.25 ≈ {1.438, 5.562}
51t+9
product is multiplying, so 51 times t. Then 9 more than is +9, so it's 51t+9.
on the sixth day 46 - 16 = 30 30/5 = 6
or
16+5 =21
21+5 = 26
26 + 5 =31
31+5 = 36
36 +5 =41
41 +5 = 46
