Question

Write an expression for the perimeter of the triangle shown below

Answer 1

the three sides are 2x, 2.3x+ 14, and -0.2+15

Answer 2

the question options are
4.1x+29
4.1x-29
4.5x+29
4.5x-29

Answer 3

I assume that the third number is - 0.2x + 15 rather than - 0.2 + 15?

Answer 4

To find the perimeter, all you need to do is add those expressions together.

Answer 5

So:

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

So

= 2x + 2.3x - 0.2x + 14 + 15

= 4.1x + 29
