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.

What is an equation in slope-intercept form for the line that passes through the points (1, -3) and (3, 1)?
tensa zangetsu [6.8K]
First we need to find the slope: 

Slope formula=\frac{y2-y1}{x2-x1}

Plug in your given values from the coordinate 
Slope =\frac{1-(-3)}{3-1}

When we have 2 "-"'s together they turn into a + sign so we add. 
Slope =\frac{1+3=4}{3-1=2}
Slope =\frac{4}{2}

Simplify (in this case divide) the slope: 
Slope =2

 slope-intercept form is: 
y=mx+b 
Where m=slope
b=y-intercept

So far we have:
y=2x+b 

To find b all we have to do is pick any given coordinate and plug it in: 
I chose (3,1) 

so we plug that in the equation
1=6+b 
 
Now solve for b:
1=6+b
subtract 6 from both sides 
b=-5  

Final answer: 
y=2x-5 (D)
