Answer 4

Well um lets see here...
(3x - 4) - (6x)
So umm
What's 3 - 6?

Answer 5

wait. it would be -3x-4

Answer 6

I would say...What about you Rush?

Answer 7

This is easy though !
we know these:
\[g(x)=6x \] and \[f(x)=3x+4\]
so we are asked to find g(x)-f(x)
we just have to substitute the values given in to this.
That is 6x-(3x+4) = 6x -3x-4 = 3x-4
So the answer would be the last one !

Answer 8

Ohhh Combine like terms...My bad!
I'm not good at these

Answer 9

they have asked us for g(x)-f(x) not f(x)- g(x)
