Write four different expressions for the perimeter of a pentagon whose sides are all s - 2 units long.

1)

2)

3)

4)

Step-by-step explanation:

1) By definition, a pentagon is a polygon which has five sides and five vertices.

2) The perimeter of a pentagon can be calculated by adding the lenght of its sides. Therefore you can write the following expression:

3) Or you can calculated by multiplying the lenght of one side by 5:

 4) You can also write it in this form:

5) Or simplified:

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .
