Find the intersection A∩B, given A= {7, 8, 9, 10} and B= {9, 10, 11, 12}.

A∩B={7,8,9,10}∩{9,10,11,12}

={9,10}

step-by-step explanation:

in geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. by extension, a line and a plane, or two planes, in three-dimensional euclidean space that do not share a point are said to be parallel.
