To get the union of two sets of numbers, all you do is combine the numbers from least to greatest. If a number repeats in the 2 sets, you only put it once.
A set is said to be a union of two sets A and B which has the elements present in the set A and B or in both. Union of two sets A and B will be denoted by A ∪ B.
For the two given sets M = (1, 7, 10, 11, 15) and N=(5, 15), their union M ∪ N will contain all the elements from the two sets but none of the elements will be repeated.
If you go 3 blocks East and 4 north, they are like the straight sides of a triangle, so to find the diagonal distance, or the shortest distance, you would find the diagonal side of a triangle it is A squared + B squared = C squared
So 3x3 = 9 And 4x4 = 16 16+9=25 And the square root of 25 is 5
Please correct me if I am wrong and have a good day
