Answer:
YES IT IS A PERFECT SQUARE
Step-by-step explanation:
equate the equation to zero
x^2+8x+16=0
c is the product while the coefficient of b is the sum
P=16
S=8
find a pair of numbers that the product is 16 and the sum is 8
the numbers are (4,4)
(x^2+4x) (4X+16)
ignore 8x and arrange as shown above
then bracket the equation
x(x+4)+4(x+4)
you simplify and remain with (x+4) (x+4)
having similar roots making it a perfect square

First of all, you need to know that profit is the difference between selling price and cost price. In this problem, profit is equal to the markup. Total profit is equal to the profit on each car multiplied by the number of cars sold.
The profit on each car is 2000 -400n, where n is defined in the problem statement as the number of markdowns (of $400).
The number of cars sold is 20 +6n. (Starting at 20, increasing by 6 for every markdown.)
The total monthly profit is the product of these binomials.
.. P(n) = (2000 -400n)*(20 +6n)
.. P(n) = -2400n^2 +4000n +40,000 . . . . . . selection C

Matching functions to data points is often just a matter of trying them to see which fits. The first two function both match points (0, 2) and (1, 6). Functions C and D fail to match (1, 6).
Only the second function matches (2, 18).
The appropriate choice is
.. B. y = 2(3)^x
