Answer:
The perimeter of the quadrilateral is 30 cm.
Step-by-step explanation:
To circumscribe implies drawing a required figure around a given figure, while to inscribe means drawing a required figure inside a given figure. From the question, the quadrilateral is circumscribed around the circle.
And given that the sum of the lengths of its two opposite sides is 15 cm.
The perimeter of a figure is the sum of the length of the sides of the figure. For this quadrilateral, the sum of opposite sides are equal.Thus;
Perimeter of the quadrilateral = 2(l+b)
= (l + b) + (l + b)
= 15 + 15
= 30
The perimeter of the quadrilateral is 30 cm.

⇒Associative property of Addition is applied for three real numbers.For, any three real numbers, A, B and C
≡A+B+C=A+(B+C)=(A+B)+C=(A+C)+B→→→Associative Property of Addition
that is , we can add any two numbers first and then the third number with them.
⇒Also, Commutative Property of Addition of two numbers says that for any two numbers , A and B
≡A+B=B+A
We have to find equivalent expression using Associative Property of the sum of set of three numbers
→→(13+15+20)+(20+47+18)
Answer Written by Jerry
→(20+13+15)+(20+47+18)
Answer Written by Layla
→(20+47+18)+(13+15+20)
The Expression Written by Keith and Melinda is Incorrect,because they haven't used the bracket Properly, as associative property says that you can add any two numbers first and then the third number among three numbers.
→→Number of Students who has applied the Associative property Correctly

17. The variable "a" represents the age of the child
18. The variable "A" represents the adult dosage
19. The prescribed dosage of the medicine for the 6-year-old child is 60 milligrams.
Work: C=6/(6+12)·180
C=6/(18)·180
C=60
