108, you can find it by finding out how many rooms per day she can clean, which happens to be 12, and then multiply 12 and 9 to get 108
or you can set up a proportion if you know how to do that
Step-by-step explanation:
A regular megagon is repr {1,000,000} and can be constructed as a truncated 500,000-gon, t{500,000}, a twice-truncated 250,000-gon, tt{250,000}, a thrice-truncated 125,000-gon, ttt{125,000}, or a four-fold-truncated 62,500-gon, tttt{62,500}, a five-fold-truncated 31,250-gon, ttttt{31,250}, or a six-fold-truncated 15,625-gon, tttttt{15,625}. A regular megagon has an interior angle of 179.99964°. The area of a regular megagon with sides of length a is given by

The permutation equation is true for all integers n ≥ 3
<h3>How to prove the equation?</h3>
We have:
Apply the following permutation formula
So, we have:
Evaluate the difference
Expand
Multiply through by (n - 3)!
Expand
Divide through by n!
Take the LCM
Evaluate the like terms
Both sides of the equations are the same.
Hence, the permutation equation is true for all integers n ≥ 3
