Dan isn’t correct it’s either c or d
It should be 20x because you multiply what’s on the outside (5) with what’s on the inside (4x) which Is also called distributing. :)
Answer:
Step-by-step explanation:
if (x,y) is the centroid. Then x=(x1+x2+x3)/3,y=(y1+y2+y3)/3
5.
x=(-2+4+10)/3=4
y=(6+0+6)/3=4
centroid=(4,4)
6.
x=(3+5-2)/3=2
y=(3-1+1)/3=1
centroid=(2,1)
