We are given a trapezoid TRHY.
Height of the trapezoid = 13 units.
b1 = 21 units and
Area = 215 units squares.
We need to find the length of b2.
We know formula for area of a trapezoid.

Plugging values in formula.
215 =
(21+b2)× 13.
215 = 6.5(21+b2)
Dividing both sides by 6.5, we get

33.08 = 21+b2.
Subtracting 21 from both sides, we get
33.08-21 = 21-21+b2
b2 = 12.08.
<h3>Therefore, length of b2 is 12.08 units.</h3>
Answer:
$9.10
Step-by-step explanation:

455 ÷ 50 = 9.1. The student tickets cost $9.10. (I think)
(9x-2) - (5x+6) =
4x-8 , this is your profit function
The slope of the line containing the points is 28... we need the negative reciprocal of this for the slope of line perpendicular..
So the slope would be: choice B
