36x2(for the total amount of yarn for the width) would be 72. 112-72=40. Since it is a rectangle and the width should both be the same size, the length should be 20 inches. (20+20+36+36=112, so 20 inches is the correct answer.
Since you are subtracting 2 logs, you write the single log as a quotient.
Answer:
B
Step-by-step explanation:
The square root of 21 will be halfway between 4 and 5. 4.58 ~ 4.6
The square root of 17 will be closer to 4 than 5. 4.12 ~ 4.1
3Pi/2 will beclose to 5 than 4. 4.71 ~ 4.7
4.1, 4.6, 4.7
That is B.
Set up a proportion.
(8.75/5)=(x/2)
5x=2*8.75
5x = 17.5
x= 3.5
