Write and expression to find the perimeter of a rectangle with a length of 8 mm and width of x mm
Mrrafil [7]

Answer:

P=16+2x

Step-by-step explanation:

The formula for finding the perimeter of a rectangle is P=2l+2w.

Plug the length of 8 and the width of x into the formula.

You'll get P=2(8)+2(x).

Multiply. 2•8=16 and 2•x=2x.

Your expression is P=16+2x.

I hope this helps.

Look at the angles for all regular polygons. As the number of sides increases, do the measures of the angles increase or decreas
Verdich [7]

Answer:

As the number of sides increases, the measures of the angles increase

see the explanation

Step-by-step explanation:

we know that

The measure of the interior angle in a regular polygon is equal to

x=\frac{(n-2)}{n}(180^o)

where

n is the number of sides of the regular polygon

x is the measure of the interior angle in a regular polygon

we have that

<u><em>Examples</em></u>

<em>A triangle</em>

n=3 sides

x=\frac{(3-2)}{3}(180^o)=60^o

<em>A square</em>

n=4 sides

x=\frac{(4-2)}{4}(180^o)=90^o

<em>A pentagon</em>

n=5 sides

x=\frac{(5-2)}{5}(180^o)=108^o

<em>A hexagon</em>

n=6 sides

x=\frac{(6-2)}{6}(180^o)=120^o

so

n ----> 3,4,5,6...

x ----> 60°,90°,108°,120°,...

As the number of sides increases, the measures of the angles increase

The pattern is x=\frac{(n-2)}{n}(180^o)
