Answer:
B. A( L) = L² - 6L
Step-by-step explanation:
A rectangle has 2 sides, length and width.
length = L
width = L - 6
Area = length × width
= L(L - 6)
= L² - 6L
The correct choice is B.
B. A( L) = L² - 6L
Put all of the numbers you have (starting from the smallest number to the biggest) in a line. Then the number in the middle is the median.
The LCM of x+3 and x-4 is x² - x - 12

Simplify further using equations calculator to get the answer as attached below:
Time Distance Distance / Time
2hrs 90 miles 90 miles / 2 hrs = 45 miles / hr
3hrs 135 miles 135 miles / 3 hrs = 45 miles / hr
5hrs 225 miles 225 miles / 5 hrs = 45 miles / hr
6hrs 270 miles 270 miles / 6 hrs = 45 miles / hr
Constant of proportionality is 45 miles / hr. This is the same for the four values. The unit rate is also 45 miles / hr.
Let us assume the Distance , d is directly proportional to Time, t
d α t
d = kt
Constant of proportionality is k which is D/T
d = 45t
