Given: Set A=4,5,7 Set B=5,9,12 What is A uu B ? {4,5,7,9} {5} {4,7} {4,5,7,9,12}

Identify Elements: Identify the elements in set A and set B. Set A = {4, 5, 7} Set B = {5, 9, 12}Determine Union: Determine the union of sets A and B, which is the set of all elements that are in A, in B, or in both A and B. A ∪ B = {4, 5, 7} ∪ {5, 9, 12}Combine Elements: Combine the elements without repeating any element, since sets do not contain duplicates. A ∪ B = {4, 5, 7, 9, 12}

Identify Elements: Identify the elements in set $A$ and set $B$ . $\text{Set } A = \{4, 5, 7\}$ $\text{Set } B = \{5, 9, 12\}$
Determine Union: Determine the union of sets $A$ and $B$ , which is the set of all elements that are in $A$ , in $B$ , or in both $A$ and $B$ . $A \cup B = \{4, 5, 7\} \cup \{5, 9, 12\}$
Combine Elements: Combine the elements without repeating any element, since sets do not contain duplicates. $\newline$ $A \cup B = \{4, 5, 7, 9, 12\}$
