Question

If the perimeter of a regular pentagon can be expressed as 10s - 20, determine the length of each side.

50 s - 100
5 s - 10
s - 2
2 s - 4

Answer 1

2 s - 4

Explanation:

Answer 2

2 s - 4

Explanation:

A Regular pentagon means that it has 5 evenly lengthen sides. In other words, the shape with 5 sides has lengths are equal to each other.

Because the total perimeter as mentioned of the pentagon is 10s - 20,

dividing it by 5 should find the length of each side!

Equation: (10s - 20) / 5

Once you finish dividing each digit inside the bracket you are done!

= 2s - 4

So that leaves us with 2s-4
