Let G = {5, 10, 15} and H = {5, 10, 12, 15}. What is G ∪ H? Choices: (A){12} (B){10, 15} (C){5, 10, 15} (D){5, 10, 12, 15}

Understand concept of union: Understand the concept of union of sets. The union of two sets G and H, denoted by G ∪ H, is the set of elements that are in G, in H, or in both G and H.List elements of set G: List the elements of set G. G = {5, 10, 15}List elements of set H: List the elements of set H. H = {5, 10, 12, 15}Combine elements of both sets: Combine the elements of both sets without repeating any elements to find G ∪ H. G ∪ H = {5, 10, 15} ∪ {5, 10, 12, 15} = {5, 10, 12, 15}Match with given choices: Match the result with the given choices. The correct choice that represents the union of sets G and H is (D){5, 10, 12, 15}.

Understand concept of union: Understand the concept of union of sets. The union of two sets $G$ and $H$ , denoted by $G \cup H$ , is the set of elements that are in $G$ , in $H$ , or in both $G$ and $H$ .
List elements of set G: List the elements of set $G$ . $G = \{5, 10, 15\}$
List elements of set H: List the elements of set $H$ . $H = \{5, 10, 12, 15\}$
Combine elements of both sets: Combine the elements of both sets without repeating any elements to find $G \cup H$ . $\newline$ $G \cup H = \{5, 10, 15\} \cup \{5, 10, 12, 15\} = \{5, 10, 12, 15\}$
Match with given choices: Match the result with the given choices. $\newline$ The correct choice that represents the union of sets $G$ and $H$ is (D) $\{5, 10, 12, 15\}$ .
