Answer:

Step-by-step explanation:
For it to be a parallelogram, opposite sides have to be of same length.
Using the expressions given, we can make 2 equations:
<u>Equation 1:</u>

<u>Equation 2:</u>

<em>Solving equation 2, we have x:</em>

<em>Plugging this value of x into equation 1, we can solve for y:</em>

So,

There are 6 letters in the word "autumn" so
6! = 6*5*4*3*2*1 = 720
represents the number of ways to arrange the letters (order matters)
Note how there are two letter "u"s here which can't be told apart. If we could tell them apart, then the answer would be 720. However, we can't tell them apart. So we're doubly counting things. To undo this, we divide by 2
720/2 = 360

Final Answer: 360
