Answer:
$60 for a noble fir, and $40 for a douglas fir
Step-by-step explanation:
Let x represent the number of noble fir trees
Let y represent the number of douglas fir trees
We can set up a system of equations to solve this problem
5x + 3y = 420
12x + 9y = 1080
We can use elimination method to solve this. 9 is a multiple of 3, so we'll multiply the first equation by -3 to get...
-15x - 9y = -1260
12x + 9y = 1080
Now add them together...
-3x = -180 now solve for x...
x = 60
If x = 60, them
5(60) + 3y = 420 now solve for y
300 + 3y = 420
3y = 120
y = 40
The horizontal yellow are is : 2(x+3) = 2x + 6
The vertical yellow are is : x(x+2+x) = x(2x+2) = 2x² + 2x
Total area = 2x + 6 + 2x² + 2x = 2x² +4x + 6 (answer B)

Answer:
Step-by-step explanation:
We know that a rational number cannot have roots. All of the answer choices cannot be simplified except for , which can become 1. Therefore, our answer is .
Given:
Consider the given function is:
To find:
The average rate of change of the function over the interval 
.
Solution:
The average rate of change of the function f(x) over the interval [a,b] is:
We have,
At 
,
At 
,
Now, the average rate of change of the function f(x) over the interval is:
Therefore, the average rate of change of the function f(x) over the interval is -3.
