Answer:
6xy+4x
Step-by-step explanation: You start off by gathering the like terms (which are 9xy & -3xy) and then you just keep 4x there. You then subtract 9xy-3xy=6xy and bring down the 4 since it has no like terms. So it’s 6xy+4x.
Answer:
Option B is correct

Step-by-step explanation:
Given that:
and
are supplementary.
prove that: 
It is given that:
and
are supplementary.
By definition of supplementary
⇒
.....[1]
From the figure, you can see that:
and
are also supplementary.
⇒
.....[2]
By [1] and [2] we have;
⇒
Simplify:

Since ∠2 and ∠3 are corresponding angles.
Corresponding angles states when the two lines are parallel, then Corresponding Angles are equal and vice versa.
by definition we have;
proved!
