Answer:
- 3 1/4
- 10.6
- 3 1/3
Step-by-step explanation:
- <em>The distance = number to the right - number to the left</em>
1..................................................................
- -2 1/2 - (-5 3/4) = -5/2 + 23/4 = - 10/4 + 23/4 = 13/4 = 3 1/4
2...................................................................
- 8.4 - (-2.2) = 8.4 + 2.2 = 10.6
3...................................................................
- -3 2/3 - (- 7) = -11/3 + 7 = - 11/3 + 21/3 = 10/3 = 3 1/3

Answer:
B ∪ C = (-∞, ∞)
B ∩ C = [1, 7)
Step-by-step explanation:
B ∪ C: The union of two sets or intervals is the set of elements which are in <em>either </em>set.
B ∩ C: The intersection of two sets or intervals is the set of elements which are in <em>both </em>sets.
<u>Interval notation symbols</u>
Square brackets [ ]: both endpoints are included in the set.
Round brackets ( ): both endpoints are excluded in the set.
Round, square ( ]: left endpoint is excluded and right endpoint is included in the set.
Square, round [ ): left endpoint is included and right endpoint is excluded in the set.
Given:
- B = {z | z ≥ 1}
- C = {z | z < 7}
Therefore,
B = [1, ∞)
C = (-∞, 7)
Therefore, B ∪ C = (-∞, ∞)
As z is either less than 7, or equal to or more than 1 then the intersection is:
B ∩ C = {z | 1 ≤ z < 7} = [1, 7)
Multiply the numbers, then take square root
Then the answer would be 44
Hope this helps!
