What is the perimeter of a regular heptagon if one side measures 3 inches

What's a regular heptagon?  "Hept-" means seven, so a "heptagon" is a seven-sided shape.  A "regular" figure's sides are all the same length.  So, each of the 7 sides are the same length.

Remember, perimeter is the sum of the lengths of all the sides in a polygon.  We know one side measures three inches, so each of the others must also measure 3 inches.  3+3+3+3+3+3+3=3*7=21 inches.

Answer: 21 inches

First, put it into point-slope form. 

Find the slope:

m=(y2-y1)/(x2-x1)
m=(-6-(-2)/(2-1)
m=(-6+2)/1
m=-4/1
m=-4

Now, put it into point-slope:

y-y1=m(x-x1)

y-2=-4(x-(-6)
y-2=-4(x+6)
y-2=-4x-24

Slope intercept form: y= mx+b

Add 2 to the other side.

y=-4x-22 <== the answer

I hope this helps!

likoan [24]
Step 1: begin by writing the formula for slope intercept form
step2: substitute the given slope for X
step3: use the order pair you given (x,y) and substitute these values for the variables x and y in the equation
step4: solve for y ( y-intercept of the graph)
step5: rewrite the original equation in step 1 substituting the slope for x and the y-intercept for y

It’s possible to build a triangle with side lengths 5 5 and 10 true or false
igomit [66]

Answer: No, the side lengths of 5, 5 and 10 would not be able to.

So the answer is FALSE.

This is because all the lengths must be enough so that when you add the side lengths they are greater then the other, all would work accept 5+5 is not greater than 10.

<h3>What are irrational numbers?</h3>

Irrational numbers are the set of real numbers that cannot be expressed in the form of a fraction, x/y where x and y are integers.

In other words, an Irrational Number is a real number that cannot be written as a simple fraction.

For example π = 3.1459....

π cannot be written as a fraction or ratio.

The decimals of irrational number goes on forever without repeating.
