I need it ASAP! Melanie had bags of sand for a sandbox. The sandbox needs bags of sand to fill it.

Orlov [11]

Melanie had 2 1/2 bags of sand for a sandbox. The sandbox needs 3 1/4 bags of sand to fill it. Melanie said she still needs 3/4 of a bag to fill it. Is that answer reasonable?

3.25 or 3 and 1/4 - 2.25 or 2 and 1/2= .75 or 3/4 so the answer is C.

Answer:

$\large \boxed{\sf \ \ -3x^3-x^2+x+18 \ \ }$

Step-by-step explanation:

Hope this helps.
