Answer 1

Answer:

B) $\frac{x^2+5x+6} {2x+5}$

Step-by-step explanation:

$\frac{1}{\frac{1}{x+2} + \frac{1}{x+3} }$

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

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

= $\frac{x(x+3)+2(x+3)} {2x+5}$

= $\frac{x^2+3x+2x+6} {2x+5}$

= $\frac{x^2+5x+6} {2x+5}$  ( which is option B )
