Answer: 4 - 5 = 4 + (-5) = -1
Step-by-step explanation: You have to make the 5 into a negative number using parenthesis and do the math.
Answer: The answer is 16√2 cm.
Step-by-step explanation: Given that there is a rectangle with length 3 times than its width. We are to find the perimeter of the rectangle.
Let 'w' represents the width of the rectangle.
Then, its length will be 3w.
Also, area of the rectangle = 24 square inches.
Therefore,

So, width = 2√2 inches and length = 6√2 inches.
Thus, perimeter of the rectangle = 4√2 + 12√2 = 16√2 cm.
After an hour (4pm to 5pm) the temperature drops 18e⁻⁰˙⁶=9.9℉, so the temperature after an hour will be 68-9.9=58.1℉.
(The change -18e⁻⁰˙⁶ is negative indicating a drop in temperature.)
