write an expression for the perimeter of the triangle shown below: A triangle is shown with side lengths labeled 2.3x plus 14, 2
x, and negative 0.2x plus 15.
2 answers:
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:
4.1x + 29
