Answer:
1) [tex]5s-10[/tex]
2) [tex](s-2)+(s-2)+(s-2)+(s-2)+(s-2)[/tex]
3) [tex]5(s-2)[/tex]
4) [tex]2(s-2)+3(s-2)[/tex]
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:
[tex](s-2)+(s-2)+(s-2)+(s-2)+(s-2)[/tex]
3) Or you can calculated by multiplying the lenght of one side by 5:
[tex]5(s-2)[/tex]
4) You can also write it in this form:
[tex]2(s-2)+3(s-2)[/tex]
5) Or simplified:
[tex]5s-10[/tex]
