Answer:
The correct features are;
2, 3, and 4
Step-by-step explanation:
2) Information carried by digital communication can be stored as digital information on electronic media such that they can be accessed with the aid of electronics and can be stored in a wide variety of recording formats including magnetic and optical media
3) Digital communication can be made over very long distance using serial communication. Fiber optics cables are used for transmitting information across continents using square waves which is a digital signal
4) Digital signals are less likely to be subjected to interference, distortion, and generation loss which is prone to analog signals, and therefore, there is less chance of signal loss when using digital communication.

Answer: 5/12
Step-by-step explanation:
Answer:
<em>Numbers: 6 and -2</em>
Step-by-step explanation:
<u>Equations</u>
This question can be solved by inspection. It's just a matter of factoring 12 into two factors that sum 4. Both numbers must be of different signs and they are 6 and -2. Their sum is indeed 6-2=4 and their product is 6*(-2)=-12.
However, we'll solve it by the use of equations. Let's call x and y to the numbers. They must comply:
![x+y=4\qquad\qquad [1]](https://tex.z-dn.net/?f=x%2By%3D4%5Cqquad%5Cqquad%20%5B1%5D)
![x.y=-12\qquad\qquad [2]](https://tex.z-dn.net/?f=x.y%3D-12%5Cqquad%5Cqquad%20%5B2%5D)
Solving [1] for y:
Substituting in [2]
Operating:
Rearranging:
Solving with the quadratic formula:
With a=1, b=-4, c=-12:
The solutions are:
This confirms the preliminary results.
