Answer:
(x + 6)(x - 2)
Step-by-step explanation:
To factor the quadratic
Consider the factors of the constant term (- 12) which sum to give the coefficient of the x- term ( + 4)
The factors are + 6 and - 2 since
+ 6 × - 2 = - 12 and + 6 - 2 = + 4, hence
x² + 4x - 12 = (x + 6)(x - 2)
Answer:

Step-by-step explanation:
SOH - CAH - TOA
Sin =
Cos =
Tan =
O = opposite, A = adjacent, H = hypotenuse
First two, use Pythagorean Theorem
If you want to calculate the angle on the last 4, use inverse of function and put in the ratio.
For example :
1) Tan Z =
(
)
Z = 36.9°

I believe the believe the answer is a1=17 C
Please correct me If I am wrong thank you :)
Step-by-step explanation:
Zone A has a higher density of rabbits.
To find the density, we need to divide the number of rabbits by the area. To find the area of each circle, you have to multiply pi (3.14) by the radius squared.
Here are the densities:
Zone A:
24000 / 1256 = 19 rabbits per square mile
Zone B:
75000 / 4069 = 18.4 rabbits per square mile
