Answer:
C i think
Step-by-step explanation:
D
use the side splitter theorem
6/12 = x/18 (replacing AQ with x)
12x = 108 (cross multiply)
x = 9
168<266
(2, -8)
(x, y)=(-3, -1)
(x1+x2)/2=-3,
(y2+y2)/2=-1,
-------------------
(x1+x2)/2=-3
(y1+y2)/2=-1
---------------------
x1-8=-6
x1=2
----------
y1+6=-2
y1=-8
234.5
Square root of 100 ~
