Answer:

No element is common to all the sets

AnBnc = { }

Step-by-step explanation:

If A= {x: xis a factor of 72}

A = {2, 3, 4, 6, 8, 9, 12, 18, 36, 72}

If B= {x: 72x+3<2x-3).

72x+3 <2x-3

72x - 2x < -3-3

70x < -6

x < -6/70

x < -3/35

x< -0.0857

If

C= {x:x<20}

C = {-∞, 19}

The intersection of the sets AnBnc = {} i.e an empty set

Note that intersection means all the elements common to the three sets
