Answer:

I think its C

Explanation:

Because if you add the bottom together you get
(1)/((1)/(2x+5) ). When you divide the bottom part flips so it would be
1*2x+5 which ends up being C

I think this is right but I may be wrong

Answer:

B

Explanation:

Simplify the sum on the denominator, that is


(1)/(x+2) +
(1)/(x+3)

multiply numerator/ denominator of first fraction by x + 3

Multiply numerator/ denominator of second fraction by x+ 2

=
(x+3)/((x+2)(x+3)) +
(x+2)/((x+2)(x+3))

=
(2x+5)/(x^2+5x+6)

The original fraction is now


(1)/((2x+5)/(x^2+5x+6) )

= 1 ×
(x^2+5x+6)/(2x+5)

=
(x^2+5x+6)/(2x+5) → B
