Question

Write an expression for the perimeter of the triangle shown below 2.3x + 14 2x -0.2x + 15

Answer 1

Answer: 4.5x+ 29 which is 3, so 3 is correct.

Explanation:

P = a+b+c

First do the ordered pairs ( add the numbers with the x to the end, then add the other numbers with no x's)

Answer 2

4.1x + 29

Explanation:

So the perimeter would be the sum of all of the sides, so:

`2.3x + 14 + 2x - 0.2x + 15\\= 4.1x + 29`
