I believe that the answer is 4.
4*2=8
4*9=36

Hope this helps!
You Need To Create An Equation Then Solve For Their Rates Of Travel.
8x^2+xy-15y^2
If you need to show work I can put it in the comments :)
Firstly you should add the like terms i.e. 5x + x. So The answer will be 6x + 2. If it requires you to factorise then take out the highest common factor i.e. 2. So factorised the answer will be 2(3x + 1).
