Write four different expressions for the perimeter of a pentagon whose sides are all s-2 units long
igor_vitrenko [27]

Answer:  The answers are given below.

 

Step-by-step explanation:  Given that all the sides of a pentagon are (s-2) units long. This clearly tells us that the pentagon is a regular one with each side equal to (s-2) units.

We are to write the perimeter of the pentagon in four different expressions.

Let 'P' represents the perimeter of the pentagon.

Since it is a regular pentagon, we can write the perimeter in following four expressions.

P = (s-2) + (s-2) + (s-2) + (s-2) + (s-2),

  = 5 × (s-2),

  = 5s - 10,

  = 5s - 5×2.

Thus, these are the four expressions for the perimeter of the pentagon.

Explain how you find the average rate of change for a linear function.<br><br> PLEASE
Olin [163]

Step-by-step explanation:

The average rate of change is constant for a linear function. Another way to state this is that the average rate of change remains the same for the entire domain of a linear function. If the linear function is y=7x+12 then the average rate of change is 7 over any interval selected. y=mx+b , where m is the slope.
