Given : Sample size : 
The proportion of individuals lease a car :
Significance level : 
Critical value : 
Then, the confidence interval of population proportion is given by :-
Hence, the confidence interval for the population proportion with a 90% confidence level=
Since the perimeter is 45 each side is 7.5 (45 divided by number of sides).
Now the picture already divided the hexagon into one triangle, and you can make another triangle in the bottom left. You can isolate the middle part into a big rectangle and the right part into two triangles.
Area of rectangle: length * width
Area of triangle: (1/2) * base * height
Answer:

Hello there!
Simply find a common term that they all have!
So they can all be divided by 6, right? So let's take a 6 out.
6 (x^2-8x-20)
Now factor the terms in the parenthesis!
6 (x-10) (x-2)
^ This is NOT your answer!!
Tip: When looking at (x^2-8x-20), look at the middle term. (-8x). Since it's negative, either (x-10) or (x-2) can be negative.
Which one is negative? Well, is the 8 positive or negative? Since the 8 is negative, the parenthesis bigger number (x-10) will be negative!
So it'll be:
6 (x-10) (x+2)
ALWAYS double check your answer by foiling! :)
Hope this helped!
