Answer:
d
Step-by-step explanation:
cannot be a or c cause it has a negative sign in front of it causing it to reflect over y axis. Cannot be B cause it doesn't have two coefficients with X. I also graphed it.
Consider the polynomial
It has three terms and their greatest common factor is ![4x^3.](https://tex.z-dn.net/?f=%204x%5E3.%20)
Since
![4x^5=4x^3\cdot x^2,\\20x^4=4x^3\cdot 5x,\\36x^3=4x^3\cdot 9,](https://tex.z-dn.net/?f=%204x%5E5%3D4x%5E3%5Ccdot%20x%5E2%2C%5C%5C20x%5E4%3D4x%5E3%5Ccdot%205x%2C%5C%5C36x%5E3%3D4x%5E3%5Ccdot%209%2C%20)
then
(you write in brackets the same sign as the corresponding term has).
Answer: correct choice is D.

Answer: 30.78181 meters</h3>
The value is approximate. Round that however you need to.
========================================================
Explanation:
- lowercase a = side opposite angle uppercase A
- lowercase b = side opposite angle uppercase B
- b = AC
Using the law of sines, we can say:
a/sin(A) = b/sin(B)
45/sin(30) = b/sin(20)
b/sin(20) = 45/sin(30)
b = sin(20)*45/sin(30)
b = 30.78181 approximately
You'll need to make sure your calculator is in degree mode.
