OK. So the answer is A. put -2 in replace of all of the x's and see if it matches. Ready?
(-2)-3*-2 = 2(4+-2) So the first answer is 4 and the second answer is also 4. Meaning they are equal so the answer is A. -2
Hope this helps

We have
tan 12.5 = 60 / adj rearrange as
adj = 60 / tan 12.5 = about 270.64 m
It would take about 5 hours for them two to work together, because if you add 2+3 you will get 5 and they are asking in total.
