Which expression illustrates the associative property of addition? 0 (3+19) - 12 = (3 + 12) - 19 0 3+ (19 - 12) = 3 + (19 + 12) O(3+19) - 12 = 3+ (19 - 12) 0 3+ (19-12) = 3 - (19 + 12) DONE

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)
