Answer:
The correct answer is option C. x² - 4
Step-by-step explanation:
Area of rectangle = Length * Width
It is given that ,
The length of a side of a rectangle is 2 units less than a number, and the width is 4 units more than the length.
Let 'x' be the number
Length of rectangle = x - 2
Width = Length + 4 = x - 2 + 4 = x + 2
<u>To find the area of rectangle</u>
Area = Length * Width
Area = (x - 2)*(x + 2) = x² - 4
Therefore option C. x² - 4 is the correct answer
<span>Tali is running at 5 miles per hour.
In 12 minutes she runs 1 mile,
in 1 minute she runs 1/12 mile,
so in 60 minutes (one hour) she would run 60/12 = 5 mph
Sandra is running at 10 miles per hour, this is twice as fast as Tali (5 mph x 2 = 10 mph).
It takes Sandra 6 minutes to run a mile.
Sandra runs 10 miles in an hour, so to run one mile would take her one tenth of an hour or 6 minutes.</span>
