For simplifying radicals, remember the product rule of radicals: √ab = √a x √b . This radical is simplified as such:
√72 = √9 x √8 = 3 x √4 x √2 = 3 x 2 x √2 = 6√2
In short, the simplified radical of √72 is 6√2.
A is always true
If a is negative the parabola wil have a minimum value
The n-th term is given by

Then we can find the common ratio from the given terms.

The appropriate choice is -1.
12/28 = 3/7
you know that it is a loss so you can ignore the wins column. Adding up both the losses of the wolves and the losses of the hawks will give you the total losses.
the answer is losses of the wolves/total losses
112.5 seconds per lap. As you need to convert the minutes to seconds, 7 x 60 = 420 + 30 = 450
450/4 = 112.5
