4/9 plus 2/5 would be 38/45, and the work is you must change the denominators to the same thing, so you do 4/9 * 5/5, like, multiply the top and the bottom by 5, to get you 20/45, and then for 2/5, multiply the top and the bottom by 9, to get 18/45, add them to get 38/45, and it can't be simplified.
Answer:
13(3x-4y+1)
Step-by-step explanation:
Rewrite 52 as (4)(13)
Rewrite 39 as (3)(13)
![=(3*13)x+(4*13)y+13](https://tex.z-dn.net/?f=%3D%283%2A13%29x%2B%284%2A13%29y%2B13)
Then factor out the common term 13
![13(3x-4y+1)](https://tex.z-dn.net/?f=13%283x-4y%2B1%29)
That is your answer!
