<PRE><B>Question 224175</B>
Find the perimeter of this triangle.


I assume the lengths of the sides are are given below


2x
4x+15
5x-9


Step 1.  Perimeter P means adding the all three sides of the triangel.


Step 2.  Then P=2x+4x+15+5x-9=(2+4+5)x+(15-9)=11x+6


Step 3.  ANSWER:  The equation for the perimeter P in this example is P=11x+6.


I hope the above steps were helpful.
