"Factor by grouping" generally means you divide the 4 terms into groups of 2 terms.
.. (5x^2 +40x) -(x +8)
Now, you factor each group.
.. 5x(x +8) -1(x +8)
Now, you factor out the common factor, x+8.
.. (5x -1)(x +8)
The easiest to find equivalent fractions is to multiply both the numerator and denominator by the same integer.
For Example, an equivalent fraction for 9/15 is 18/30. I got this answer by multiplying 9*2=18 and 15*2=30.
Another equivalent fraction for 9/15 is 27/45 because 9*3=27 and 15*3=45.
******Note
Just make sure that you always multiply the numerator and denominator by the same number, or else your fractions won't be equivalent!!
If these permutations were in a line, then the equation would be n!. But since we are dealing with a circle, it's a little bit different, given that there is no specific beginning or end. This means that <span>you could rotate the circle around n different ways and still have the same circular permutation. Thus, this would be the expression you are looking for:
n!/n, which can be simplified as (n-1)!
The correct answer is the second option.</span>
