Respuesta :

it is D because
-24 /4n will equal -6n because the n won't go away

8m/4n will equal 2mn because you can always have two variables on one number and the n is not going anywhere

-100p/ 4n will equal -25np because of the same reason as the upper one.

so -6n + 2mn -25np is the simplified expression
The correct answer is d
