D is correct:
because of doing the correct steps:
step1: put the point of your compass on the left endpoint of the segment, A.
Open the compass to be more than half the length of the segment. Then leave a half-circle mark.
step2: do the same thing on the other point B. and find the middle point.
Answer:
3 is the root of the equation.
Step-by-step explanation:
We have to find the root of the polynomial equation x(x-2)(x+3)=18.
We can find the same by using a graphing utility and the system of equations.
We can make two equations which are given by

Now, we plot the graph of these equations and the x-coordinate of the intersection point will be the root of the equation.
the graph has been shown in the attached file.
The intersection point is (3, 18) and the x-coordinate is 3.
Therefore, 3 is the root of the equation.
I believe it is C .... my re input results in less output
-22 = - (x - 4)
= -22 = -x + 4 (distribute the minus)
= -26 = -x (subtract 4 from both sides)
= 26 = x (divide by -1 to remove the minus from x)
so, x = 26
