if you’re good with diagrams in set theory for math 30 please help with questions 17 and 18! real answers only!!

C, and C

Step-by-step explanation:

A' means the part that excludes A and the rest of question ask us to merge A' with A and B's common point, so the diagram that represents this is in C

on the 18th question it ask us to find the common point of A and B and then C' and mark outside of this point so the answer is C once again

probably .5

i can on others if necessary.

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)
