Question

Answer 1

4.1x + 29

Explanation:

I took the test and I got it correct :)

Answer 2

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 .
