Answer:

(C). {3}

Step-by-step explanation:

$\frac{x}{2(x+1)}$ = $\frac{-2x}{4(x+1)}$ + $\frac{2x-3}{x+1}$ ( x ≠ - 1 )

$\frac{x}{2(x+1)}$ - $\frac{2x-3}{x+1}$ + $\frac{x}{2(x+1)}$ = 0

$\frac{2x-3}{x+1}$ - $\frac{x}{(x+1)}$ = 0

$\frac{x-3}{x+1}$ = 0 ⇒ x = 3

Evaluate tan ( cos^-1 ( 1/8 ) ) , giving your answer as an exact value (no decimals)

$\bf cos^{-1}\left( \cfrac{1}{8} \right)=\theta \qquad \qquad cos(\theta )=\cfrac{\stackrel{adjacent}{1}}{\stackrel{hypotenuse}{8}}\impliedby \textit{let's find the \underline{opposite}} \\\\\\ \textit{using the pythagorean theorem} \\\\ c^2=a^2+b^2\implies \sqrt{c^2-a^2}=b \qquad \begin{cases} c=hypotenuse\\ a=adjacent\\ b=opposite\\ \end{cases} \\\\\\ \pm\sqrt{8^2-1^1}=b\implies \pm\sqrt{63}=b ~\hfill tan(\theta )=\cfrac{\stackrel{opposite}{\pm\sqrt{63}}}{\stackrel{adjacent}{1}} \\\\\\ ~\hspace{34em}$
