The perimeter of a regular octagon is p. write an expression that represents the length of one side of the octagon?

math  JJ, Wednesday, February 20, 2013 at 7:14pm
An octagon has 8 sides.
Perimeter = 8 times length of 1 side.

math  andrew, Wednesday, February 20, 2013 at 7:16pm
so is it 8 times x?
8*x?

math  JJ, Wednesday, February 20, 2013 at 7:17pm
no we have p = perimeter
You want to use p and 8.
Do you multiply or divide?

math  lina, Wednesday, February 20, 2013 at 7:19pm
oh you multiply?

math  andrew, Wednesday, February 20, 2013 at 7:19pm
YOU MULTIPLY!
right..?

math  lina, Wednesday, February 20, 2013 at 7:20pm
yes

math  JJ, Wednesday, February 20, 2013 at 7:20pm
no, you would divide.
Let's say the perimeter is 40?
Would it make sense to say a side is 320
or does it makes sense to say a side is 5?

math  andrew, Wednesday, February 20, 2013 at 7:21pm
that makes sense so it would be 8/p then?

math  JJ, Wednesday, February 20, 2013 at 7:22pm
NO.. p/8
40/8

math  andrew, Wednesday, February 20, 2013 at 7:24pm
Ohhhhh that makes much more sense thank you so just p/8 or p/8=x ?

math  JJ, Wednesday, February 20, 2013 at 8:09pm
Right. Glad it makes sense.
