Answer:
The temperature needs to decrease 71° - 50° = 21° that at least not greater than 50°F
As we know, the device decrease the temperature down 3.5° every hour, so
21 : 3.5 = 6 hour
Call x is the hours we need to wait to let the device decrease, we have
x > 6
Answer: D
Step-by-step explanation:
To find the perimeter of the square, you want to first find the length of each side. Since the figure is a square, we know that each side is equal to each other. We can set the expressions equal to each other to find x.
[subtract both sides by 1/2x]
[add both sides by 1]
[multiply both sides by 4]

Now that we know x, we can plug it into each expression to find teh length of each side.
[multiply]
[subtract]

Now that we know each side is equal to 23, we can add all the sides together to find the perimeter.
23+23+23+23=92 or 23×4=92
Since we know that the perimeter is 92 units, the answer is D.
