Question

write an expression for the perimeter of the triangle shown below: A triangle is shown with side lengths labeled 2.3x plus 14, 2x, and negative 0.2x plus 15.

Answer 1

The perimeter is just the sum of all the side lengths.
So let's get to work and addum up:

                              (2.3x + 14) + (2x) + (-0.2x + 15)

Add up all the x's:  (2.3x + 2x - 0.2x) =  4.1x

Add up all the ordinary numbers:  (14 + 15) = 29

So the perimeter is simply    4.1x + 29 .
 

Answer 2
