<span>A semicircle is cut out of a rectangular paperboard 27 long and 20in wide, as shown below. What is the perimeter of the paperboard that remains after the semicircle is removed</span>
Answer:
A: 2+27=29
B: The sum of the integers 2 and 27 is the integer 29, which demonstrates that integers are closed under addition.
Step-by-step explanation:
Since, closed property of addition for a set A is defined as,
∀ x, y ∈ A ⇒ x + y ∈ A,
∵ Set of integer is closed under multiplication,
If Z represents the set of integer,
Then 2, 27 ∈ Z ⇒ 2 + 27 = 29 ∈ Z,
Hence, the equation illustrates given statement,
2+27 = 29
The statement that correctly explains given statement,
The sum of the integers 2 and 27 is the integer 29, which demonstrates that integers are closed under addition.c

Step-by-step explanation:
19-4c=17
19-17=4c
2=4c
2/4=c
therefore, c=1/2
