the correct option is answer choice D, because there are multiple 2's in the x column with different f(x) values.
I see the answers,but where is the problem (equation that needs to be solved)
Answer:
4.875?
convert it into an improper fraction
Answer:

Step-by-step explanation:
f(x)= - 3x
g(x) = x+2
(f•g)(x)
f(x) • g(x)
plug in
-3x • x+2
-3x(x+2)
distribute the -3x

hope this helps!
For this case the first thing you should know is that we have the following definition:
V = I * R
Where,
V: voltage
I: current
R: resistance
Therefore, by clearing the Resistance we have:
R = V / I
Substituting the values:
R = 12/48
R = 1/4 ohms
Answer:
The value of the resistance is:
R = 1/4 ohms
