Answer:
x = 12
Step-by-step explanation:
The line joining the mid points of the non- parallel sides is parallel to the parallel sides and is equal to half the sum of the parallel sides, hence
5x - 20 =
(2x + 6 + 4x + 2)
=
(6x + 8) ← distribute, giving
5x - 20 = 3x + 4 ( subtract 3x from both sides )
2x - 20 = 4 ( add 20 to both sides )
2x = 24 ( divide both sides by 2 )
x = 12
Answer: what is the distance between points A and B? 14 Units
Step-by-step explanation: The first thing that you need to do is to draw the number line shown, then we mark the two points mentioned: -2 and 12 and encircle them, following this we are going to count to the right, starting on point A, -2, and finishing on point B, 12. After we count, we are going to see that the distance between the two points is 14 units.
