Answer:
39 inches
Step-by-step explanation:
5x+x=234
6x=234
234/6=39
x=39 inches
Answer:
See below.
Step-by-step explanation:
I'm assuming these questions are about the Midline Theorem (segment AL joins the midpoints of the non-parallel sides.
♦ The midline's length is the average of the lengths of the top and bottom parallel sides.

Use this equation and substitute values given in each problem, then solve for the missing information.
1. AL = x, CE = 9, OR = 5

2. AL = <em>m</em> - 4, CE = 15, OR = 17

3. OR = y + 5, AL = 15, CE = 18

The point (2, -5) would not be one of the correct vertices of the reflected shape.
When we reflected a shape across the line y=x, we just replace the x's with y's and y's with x's.
Our new points are (5, 2) (4, 6) and (3, 3). None of the points contain negative numbers.
