The perimeter of a triangle is 195 mm.If the lengths of the sides are consecutive odd integers,find the length of each side.
what steps do i need to do in order to get the answre?
Perimeter= L + L+2 + L+4
solve for L. That is the short side. THen add two for the next side, and add two again for the last side.
x = first odd integer
x + 2 = second odd integer
x + 4 = third odd integer
Therefore:
x + x + 2 + x + 4 = 195
Solve for x. Don't forget to list all sides!
I hope this will help get you started.

3x+6=195
6 6
3x=189
divide by 3
on both sides
and you get x=63
