To find the answer of this problem, we need to distibute and multiply all of the numbers with each other.
2x * x + 2x * 1 + 9 * x + 9 * 1
= 2x^2 + 2x + 9x + 9
= 2x^2 + 11x + 9
The answer would be the first option.
Hope this helps!
Answer:
The region with the highest population density is Binky Lee
The region with the lowest population density is Cheslen
Step-by-step explanation:
we know that
The <u><em>population density</em></u> is the number of people per unit of area
so
Find out the population density for each region
<em>Bear Creek</em>

<em>Binky Lee</em>

<em>Cheslen</em>

<em>Crow's Nest</em>

so
Cheslen < Crow's Nest < Bear Creek < Binky Lee
therefore
The region with the highest population density is Binky Lee
The region with the lowest population density is Cheslen
We are to find the value of

First we evaluate tan(π/4). The value of tan(π/4) is 1.
So,

sin(π/2) = 1
So,

Thus, we can write:

radians.
So, the answer to this question is π/2 radians.
