I believe its D but im not 100% someone explain to me :/

Answer 1

im absolutely positive it is D i promise

Answer 2

It is B because your question says 12 LESS THAN twice a number

First you have to put the (twice a number) which would be 2n or 2•n either would work....

Then subtract out 12 from 2n or 2•n
As a result it is 2n-12 or 2•n-12
