The parallelogram shown represents a map of the boundaries of a natural preserve. walking trails run from points a to c and from points b to d. the measurements shown represent miles.

parallelogram a b c d is shown. diagonals are drawn from point a to point c and from point d to point b and intersect at point e. the length of d e is y + 2, the length of e b is 3 y minus 4, and the length of e c is 2 y minus 3.

what is the sum of the lengths of the two trails?

6 miles
12 miles
16 miles
36 miles

Ithink is the abswer b

First, think of what you know. you know that the number t the end of the equation will need to be subtracted because it is the money he lost from buying the lawn mower. and your first two weeks have negative profit, so that tells you that c and d are wrong. now you can plug any of the weeks into a and b to see which one works. i'll start with plugging week 1 into a.this isn't right because it says your answer for week one should be -90.so now we need to try the same thing with b.this one got you the right answer, (sometimes if you only check with one of the weeks multiple will work so you need to check with more of the weeks, but it worked out fine here)this means that b is the correct answer.let me know if you need more clarification. i hope this : )
