Question

for which set of points is one point the midpoint of the segments joinging the other two points?
a= (0,0), (5,6), (10,3)
b=(0,3), (2,6), (-2,0)
c=(4,6), (8,12), (16,24)
d=(2,0), (2,6), (2, -3)

which expression is the factored form of 1x+2x+6?
a=3x+6
b=2(x+3)
c=3(x+2)
d=3(x+6)

Answer 1

a) none. could have been d if third point was (2,3)
