The missing side x would be 13. I figured this out by seeing how to get 21 from 3 which is 3 •7 then I did the same with all the others sides and they all added up to __•7 so all you have to do is divide 91 by 7 and you will get 13.

I hope this helped you understand!!:):) Sorry if you couldn’t understand how I explained it

x^2 - 9 = (x + 3)(x -3)

3x - 9 = 3(x - 3)

and

Common denominator would be 6(x+3)(x - 3)

Answer: 6(x+3)(x - 3)
