I have another set of choices here:
A. {0.5, 1, 2}
B. {1, 2, 4}
C. {1, 2, 3, 4, 5}
<span>D. {0}
</span>
If you multiply two numbers from a closed set the answer is in the set.
<span>So A is not closed because 2 x 2 = 4 which isn't in the set. Only 0.5, 1, and 2 are in set A. </span>
<span>Try multiplying the largest numbers in sets B, C, and D by themselves. You will soon discover the closed set.</span>

To find the unit price, divide the total price by the total weight.
4.60 / 2 = 2.30
So, the unit price is $2.30 per liter of milk.

Given:
The parallel sides of a trapezium are 28.7 cm and 22.3 cm.
The distance between parallel sides is 16 cm.
To find:
The area of a trapezium.
Solution:
The area of the trapezium is:
Where, 
are parallel sides and 
is the vertical distance between the parallel sides.
Putting 
in the above formula, we get
Therefore, the area of the trapezium is 408 square cm.
Answer:
a=35, b=14, c=5
Step-by-step explanation:
b+6=20, b+6-6=20-6, b=14
4c-6=14, 4c-6+6=14+6, 4c=20, 4c/4=20/4, c=5
a triangle's angles always add up to 180, 180-55-90(the square means right angle)=35
