UmmHELP Me I Dont Get It class=

Sagot :

Answer:

I think its C

Step-by-step explanation:

Because if you add the bottom together you get [tex]\frac{1}{\frac{1}{2x+5} }[/tex]. When you divide the bottom part flips so it would be [tex]1*2x+5[/tex] which ends up being C

I think this is right but I may be wrong

Answer:

B

Step-by-step explanation:

Simplify the sum on the denominator, that is

[tex]\frac{1}{x+2}[/tex] + [tex]\frac{1}{x+3}[/tex]

multiply numerator/ denominator of first fraction by x + 3

Multiply numerator/ denominator of second fraction by x+ 2

= [tex]\frac{x+3}{(x+2)(x+3)}[/tex] + [tex]\frac{x+2}{(x+2)(x+3)}[/tex]

= [tex]\frac{2x+5}{x^2+5x+6}[/tex]

The original fraction is now

[tex]\frac{1}{\frac{2x+5}{x^2+5x+6} }[/tex]

= 1 × [tex]\frac{x^2+5x+6}{2x+5}[/tex]

= [tex]\frac{x^2+5x+6}{2x+5}[/tex] → B
