Answer: 3rd option
Step-by-step explanation:
Let’s look at the denominator. 2x-yep. (x-4) is also there.
There is 2 “x” denominators and 3 + 4 = 7. So it’ll look like 7x*2.
Then, there needs to be an + and - sign in the answer.
Finally, the third option is the only one that incorporates all three factors.
Hope this helps!
