Match the following. given a = {1, 2, 3, 4, 5} b = {2, 4, 6} c = {1, 3, 5} 1. a ∪ b {1, 2, 3, 4, 5, 6} 2. a ∪ c {2, 4} 3. a ∩ b {1, 3, 5} 4. a ∩ c null, or empty set 5. b ∩ c {1, 2, 3, 4, 5}

Given sets,

A = {1, 2, 3, 4, 5},

B = {2, 4, 6},

C = {1, 3, 5}

1. A ∪ B = all elements of sets A and B

= {1, 2, 3, 4, 5, 6}

2. A ∪ C = all elements of sets A and C,

= {1, 2, 3, 4, 5}

3. A ∩ B = common elements of sets A and B

= { 2, 4 }

4. A ∩ C = common elements of sets A and C

= { 1, 3, 5}

5. B ∩ C = common elements of sets B and C

= ∅ ( null or empty sets )

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
