Question

The perimeter of a regular octagon is p. write an expression that represents the length of one side of the octagon?
JJ
An octagon has 8 sides.

Perimeter = 8 times length of 1 side.
andrew
so is it 8 times x?

8*x?
JJ
no we have p = perimeter
You want to use p and 8.

Do you multiply or divide?
lina
oh you multiply?
andrew
YOU MULTIPLY!
right..?
lina
yes
JJ
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?
andrew
that makes sense so it would be 8/p then?
JJ
NO.. p/8

40/8
andrew
Ohhhhh that makes much more sense thank you so just p/8 or p/8=x ?
JJ
Right. Glad it makes sense.

yo what up
