Yessenia simplified an expression as shown below: Given: x+6+3(x+4)
Step 1: x+9(x+4)
Step 2: x+9x+36
Step3: 10x+36
In which step did Yessenia make a mistake?
What should she have done instead?

step-by-step explanation:

the answer is ! ?

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)
