<h2>Intersection and Union of Sets</h2><h3>Answer:</h3>

$A \cup B = \{ a, b, c, d, e \}$

$B \cap C = \{ d, e \}$

$A \cup C = \{ a, b, c, d, e, f \}$

<h3>Step-by-step explanation:</h3>

Given:

$A = \{ a, b, c, d \}$

$B = \{ b, d, e \}$

$C = \{ d, e, f \}$

The Union ( $\cup$ ) of sets $A$ and $B$ is just a set containing all the elements of sets $A$ and $B$ . However, elements that are present in both sets should not repeat in the Union of Sets as the elements of a set should distinct be from each other.

Part i:

$A \cup B \\ \{ a, b, c, d \} \cup \{ b, d, e \} \\ \{ a, b, c, d, e \}$

The Intersection ( $\cap$ ) of sets $A$ and $B$ is just a set containing all the elements that are both present in sets $A$ and $B$ .

Part ii:

$B \cap C \\ \{ b, d, e \} \cap \{ d, e, f \} \\ \{ d, e \}$

Part iii:

$A \cup C \\ \{ a, b, c, d, \} \cup \{d, e, f \} \\ \{ a, b, c, d, e, f \}$

AnnyKZ [126]

Answer:

More sod is needed

Step-by-step explanation:

Well we know that 3/4 of a bag of sod covers 55 ft^2 then if we divide 55 by 3 we get 18.3333 we take that and multiply by 4 to get 73.333 or the amount one bag of sod can cover

73.333*3 cuz 3 bags of sod is 220 ft^2

She needs more sod
