Hi!
a: <em>F </em><em>n </em><em>G </em>=(Intersection) {4,6,8,10}
b: <em>F </em><em>n </em><em>H </em>={empty set}
Because there is no common element between the elements of set F and the elements of set H.
Note: It may not be very clear as I don't speak English.

Answer:
number of ways = 120
Step-by-step explanation:
The number of ways five children can pose for a photograph line up in a row is given by the number of permutations of 5 elements in 5 different positions (positions in the line), then
number of ways = number of permutations of 5 elements = 5! = 5 * 4 * 3 * 2 * 1 = 120
Since the first children that occupies the line can be on any of the positions (5 positions) , but then the second one can choose any of the 4 remaining positions (since the first children had already occupied one) , the third can choose 3 ... and so on.
The length of rectangle is 37.5 and width is 12.5
Step-by-step explanation:
Given,
Width of rectangle = w
Length of rectangle = 3w
Perimeter of rectangle = 100
Perimeter = 2(Length+Width)
Dividing both sides by 8
Width of rectangle = 12.5
Length of rectangle = 3(12.5) = 37.5
The length of rectangle is 37.5 and width is 12.5
Keywords: Rectangle, perimeter
