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.
use the distributive property to write an equivalent expression for the perimiter of the trangle?
4+4+3h+2
To find the perimeter of a triangle when each side is expressed in terms of variables, such as 3x, -4y, or -3x, you need to add up the lengths of all three sides of the triangle. Let's break it down step-by-step:
1. Identify the three sides of the triangle and their corresponding lengths:
- First side: 3x
- Second side: -4y
- Third side: -3x
2. Add up the lengths of all three sides to find the perimeter:
Perimeter = (length of first side) + (length of second side) + (length of third side)
In this case, substitute the lengths of the sides:
Perimeter = 3x + (-4y) + (-3x)
3. Combine the like terms:
Perimeter = (3x - 3x) + (-4y)
Since 3x - 3x cancels out, we are left with:
Perimeter = -4y
Therefore, the perimeter of the triangle is -4y.
