<h2>there s a theorem called MIDPOINT THEOREM </h2>
Which means the 3rd side of the triangle is equal to 1/2 of the line drawn by joining the mid points
<h2>so AB=1/2of YZ</h2>
which means
2x-4 = 1/2×21
thus, 2(2x-4) =21
=> 4x-8 = 21
4x = 29
<h2>x= 29/4 = 7.25</h2>
68 miles to 42.5's percent of decrease is: 37.5%
Using proportions. 68 miles - 42.5 = 25.5
25.5 x
------ = -----
68 100
Cross multiply:
25.5 x 100 = 2550
68 multiply x = 68x
2550 divided by 68 = 37.5
x = 37.5%

Answer:
240
Step-by-step explanation:
You have to find the area of each indivigual side and then add all the areas together. So like 9x5 is 45 so you take 45 and multiply it by 4 since there are 4 sides identical to that side and then you get 180. Then you multiply 6x5 and that gives you 30 which you then multiply by 60, so then all you gotta do is 60+180=240.
