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

2 s - 4

Step-by-step 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

if x decreases by 4 then y increases by 10
