Find the value of x.
10
11
14
9

The mid line of a triangle is always half of the triangle's "base"

Plug all the answer choices in and see if they produce a true answer

20 = (2(10) - 8) * 2

20 = (20 - 8) * 2

20 = 12 * 2

20 ≠ 24

10 is NOT x

20 = (2(11) - 8) * 2

20 = (22 - 8) * 2

20 = 14 * 2

20 ≠ 28

11 is NOT x

20 = (2(14) - 8) * 2

20 = (28 - 8) * 2

20 = 20 * 2

20 ≠ 40

14 is NOT x

20 = (2(9) - 8) * 2

20 = (18 - 8) * 2

20 = 10 * 2

20 = 20

9 IS x!!!

Or you can do it this way:

20 = (2x - 8) * 2

Divide 2 to both sides

10 = 2x - 8

18 = 2x

x = 9

Hope this helped!
