The vertices of a triangle are A (−4, 2), B (1, 9), and C (6, −5). Find the coordinates of the intersection of the medians.

square root

step-by-step explanation:

answer: 5

step-by-step explanation:

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius

: )

the solution, from the graphing of the two lines, is (3,2), i.e., x = 3, y = 2.
