Answer:
Third answer.
Step-by-step explanation:
To simplify, we can factor 'x' from the equation, giving us:
[tex]\frac{x(1)}{x(4 + x)} = \frac{1}{x+4}[/tex]
However, we must put a domain restriction to ensure that the denominator will not equal 0. This means that 'x+ 4' cannot equal zero. Therefore, x ≠ -4.
The third answer is correct.
