Ans. 31.416
Step-by-step explanation:
Perimeter of square = 40
so each side =40/4=10
hence, the diameter of the circle will be 10 inches
so, the radius = 10/2=5
therefore, the circumference = 2π r=2*3.1416*5
=31.416
Hope u got it..!!
Answer: ![(-9, 16]](https://tex.z-dn.net/?f=%28-9%2C%2016%5D)
This is the interval from -9 to 16. Exclude -9 but include 16.
=====================================================
Work Shown:
The idea is to multiply all sides by 5, then add 1 to all sides





This converts to the interval notation ![(-9, 16]](https://tex.z-dn.net/?f=%28-9%2C%2016%5D)
note: a curved parenthesis means "do not include this value in the solution set"; while a square bracket has us include the value. So we exclude -9 and include 16.
