Answer:
72.54
Step-by-step explanation:
Use formula for trapezoid: a+b/2 * h
I'm assuming you need to evaluate/simplify the equation, so you need to isolate/get x by itself in the equation:
2(3x + 1) = 11 Divide by 2 on both sides
3x + 1 = 
[11/2 or 5.5] Subtract by 1 on both sides
[make the denominator the same to combine fractions]
3x = 
Divide by 3 on both sides
x = 
(1/2)(1/2)(1/2) = 1/8 or .125
That is your answer. Hope this helped.
