math; distributive property;perimeter of a triangl
posted by Kyra on .
How do I find the perimeter of a triangle if each side has an expression such as: 3x, and the second side let's say -4y, or the third side is -3x...something like that. Please help. I'm trying to study.
it depends on a lot of things, you have to know something about the triangle (right, or an angle, or something).
use the distributive property to write an equivalent expression for the perimiter of the trangle?
