Answer:
<em>n = 20</em>
Step-by-step explanation:
[ 180° ( n - 2 ) ] / n = 162°
180 ( n - 2 ) = 162 n
180n - 360 = 162n
18n = 360
<em>n = 20</em>
1km is 1000 m
1000m+125m-375m=750m
Area = 36 = length*width
Then, while the area is constant the product length*width is constant.
Length and area are inversely related.
That means that to keep the same product (area), length vary in inverse proportion to width.
If you increase length, widht has to decrease to satisfy this relation:
width = 36/length
Of course, you can also say: length = 36 / width.
Answer:
The answer is A.
Step-by-step explanation:
You have to multiply by converting the second fraction into upside down :
-39, -37, -35, -33, -31, -29. Odd numbers are the same just backwards ;)
