Which of the following shows an equivalent expression to
[(5.3). 12) if only the associative property was used to transform the expression?

answer: 10 meter

step-by-step explanation:

need details

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)

33/100 is what i got

11) obtuse

13)right

15) acute
