3+3= 6
6+1= 7 is your answer
First observe that x=-1 is a root of the equation. Use long division to divide x^3-3x^2+x+5 by x+1, we find that (x^3-3x^2+x+5)/(x+1)=(x^2-4x+5). Now we need to find the roots of x^2-4x+5.
x^2-4x+5=0,
x^2-4x+4=-1,
(x-2)^2=i,
x-2=i or -1,
x=2+i or 2-i.
The three roots are 2+i, 2-i, -1.
Hi, all we need to do is to divide the number of brownies by the number of students, and we will get the amount of how many would each student get.
26/15 = 1,73 brownies per student.
$9.98 * 1.095 = (that is tax; for ex. if it was 23.6 percent tax it would be 1.236)
<u><em>$10.93</em></u>
