Answer: x=4, AB=19, ED=57

Explanation:

Trapezoid midsegment formula:
(b1+b2)/(2)=Midsegment

Therefore, (4x+3+18x-15)/2=38

Multiply both sides by 2 in order to get rid of the fraction. (Multiplication property of equality)

4x+3+18x-15=76

Combine like terms.

22x-12=76

Add 12 to both sides. (Addition property of equality)

22x = 88

Solve for x

x = 4

Now, substitute x in for segment AB and ED

AB = 4(4)+3

AB= 16+3

AB= 19

ED=18(4) -15

ED=72-15

ED=57

Check your work:

(ED+AB)/2 = 38

(57+19)/2 = 38

76/2 = 38

38 = 38
