Find the smallest possible set (i. e., the set with the least number of elements) that contains the given sets as subsets. (Enter your answer using roster notation. Enter EMPTY or ∅ for the empty set.) {1, 2}, {1, 3, 4}, {4, 5, 8, 9}

each side has a different length.  

step-by-step explanation:

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.

step-by-step explanation:

9 sandwiches per hour

step-by-step explanation:

when we have a rate, we want a 1 in the denominator

27/3 = 9

27 sandwiches/ 3 hours = 9 sandwiches/hour
