Idid some work but i still can't seem to find x.

since ΔQRS similar to ΔQRP, then

SR/QR = QR/PR

x/12 = 12/(3.5+x)

x(3.5+x) = 12²

x² + 3.5x = 144

x² + 3.5x - 144 = 0

approximately 10.38

21/58.

hope to be marked brainliest

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)
