Um i would need more details
But i thing you would add those together
F,e and h,i are vertical angles i think.
Are you solving for X? If so, your answer will be x=-3. Hope this helps!

200,000 + 80,000 + 3,000 + 900 + 80
If you were to factor you would do what my teacher likes to call reverse foil so it would look like this (x-9)(x+4) so what you do is you brainsrorm to see what multiplies what to get that and 9*4=36 so that is how you factor -36 to find the -9
Hope this helps if I'm correct if not I will try to find the answer
