If it is (x-4)(x-2)3x than the answer is 3x(x^2-4x-2x+8) = 3x(x^2-6x+8) = 3x^3 - 18x^2 + 24x
If it is (x+4)(x-2)3x than the answer is 3x(x^2+4x+2x+8) = 3x(x^2+6x+8) = 3x^3 + 18x^2 + 24x
By graphing the polynomial, we conclude that there is only one real root, so the correct option is A.
<h3>
How many roots has the given polynomial?</h3>
We have the polynomial:

To see how many real roots this polynomial has, we can graph it and see how many times the graph intercepts the x-axis.
The graph can be seen below:
There we can see that there is only one intercept, so there is only one real root.
So the correct option is A.

If there are n different things in a circular arrangement, the number of ways of arranging them is (n - 1)!
The number of ways the desserts can be arranged on the circular tray is:
(7 - 1)! = 6 * 5 * 4 * 3 * 2 * 1 = 720 ways
5 + 5 + 5 + 5 + 5 + 5 = 30 (6 bills)
1 + 1 + 1 + 1 + 1 = 5 (5 bills)
30 + 5 = 35 (11 bills)
The complement would be 90-23 which is 67
