40 questions. You set up a proportion, mutiply 34 by a 100 and get 3400. Then you divide 3400 by 85 and you get ur answer. You could also try guessing by putting in random values you think are the whole number and multiplying them by 0.85. So if you guess 44 is the whole and try checking it by multiplying it by .85 and get a value thats higher than the value the percentage is equal to you try another smaller value. So if 44 doesn't work you can try 40. 40 times .85 is 34 so your answer of 40 questions is correct.

where
is the distance between points
and 
We are given that
is
and
is
, therefore the distance between the two points is:






Therefore, the distance between
and
is
units.
Factoring the expression would be 6a(2a^2+4a-1)
