The equation -2(6 - 20n) = 20(2n - 3) has no solution.
Hence the correct option is C.
Given is an equation -2(6 - 20n) = 20(2n - 3), we need to solve it for n,
Let's solve the equation step by step:
-2(6 - 20n) = 20(2n - 3)
First, distribute the -2 on the left side and the 20 on the right side:
-12 + 40n = 40n - 60
Next, let's move all the terms with "n" to one side of the equation:
-12 + 40n - 40n = 40n - 40n - 60
-12 = -60
Now, we can see that the equation is inconsistent, as there are no values of "n" that satisfy this equation.
Therefore, the correct answer is:
c. no solution

-12 + 40n = 40n - 60
40n = 40n - 60 + 12
40n - 40n = 60 + 12 (dont minus 40n - 40n yet, we can factorise it)
n(40-40) = 60 + 12
n = (60 + 12)/(40-40)
n = 60 + 12/ 0
Therefore no solution as we cannot divide by 0

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.
It has four choses and you didn't show the right one, answer is 3.
3(3-2)(3+3)=18
3(1)(6)=18
3*6=18

Compatible numbers:
400 / 10 = 40
Compatible numbers are numbers that can quickly be solved mentally. The quotient would only be an estimate since we only rounded the number to the nearest compatible number.
394.6 is nearer to 400 while 9 is closer to 10. Both numbers 400 and 10 are compatible because they can be solved quickly doing mental calculations.
