Select the statements that are true based on the following given information. d = {x | x is a whole number} e = {x | x is a perfect square < 36} f = {x | x is an even number between 20 and 30} the expression d ∪ e = e. e ∪ (d ∩ f) is {25}. f ⊂ d (e ∩ f) is the empty set. set e is infinite.

D = {x | x is a whole number} = { 0, 1, 2, 3, 4, 5, ...}

E = {x | x is a perfect square < 36} = { 0, 1, 4, 9, 16, 25}

F = {x | x is an even number between 20 and 30} = { 22, 24, 26, 28}

the reason why your question keeps getting deleted because this is not a school related question : )
