Which description is paired with its correct expression? seven less than the quotient of two and a number squared, increased by six, 7-36 12 O nine times the difference of a number cubed and three: 9(rº - 3) O eight more than the quotient of a number squared and four, decreased by seven: O twice the difference of a number cubed and eight: 2n - 8​

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)

it is 10.6 according to my calculations
