To make a rational expression equal to zero equate its numerator (up) by 0 and find the value of x
Since the given rational expression is
[tex]\frac{2x+16}{x+5}[/tex]
Since the numerator is (2x + 16), then equate it by 0 and solve to find x
[tex]2x+16=0[/tex]
Subtract 16 from both sides
[tex]\begin{gathered} 2x+16-16=0-16 \\ 2x=-16 \end{gathered}[/tex]
Divide both sides by 2
[tex]\begin{gathered} \frac{2x}{2}=\frac{-16}{2} \\ x=-8 \end{gathered}[/tex]
The answer is B
