Question 142436: Okay, the instructions say to Solve the Radical Equation...
6-√2x=-2
I know how to solve Radical Equations, but we were not told how to do ones that had a negative sign before the √. I really appreciate your help.

Question 143247: Simplify the radical √20/√4
I think I did this problem the right way, I just want to make sure I am since I have several of these to do. Here are my steps...
√20 = √4X5 = 2√5
√4 = 2
2√5/2 (You cancel out the 2)
Answer √5

Question 143530: I just want to make sure I have the right answer, if I don't could you please explain the steps to me.
Problem---Find the perimeter of a rectangle if the dimensions are length √19 + 7 and width √76.
Here is my work
“Sqrt19 + 7”^2 + “sqrt76”^2 = perimeter
19 +7 + 76 = perimeter
26 + 76 = perimeter
102 = Perimeter
Perimeter = 102

Question 143528: I just want to make sure I have the right answer, if I don't could you please explain the steps to me.
Problem---Find the area of a rectangle whose width is √2 and whose length is √40. Show your work. Write “Sqrt” to show √.
Here is my answer
Sqrt2 X Sqrt40 = Sqrt80
Sqrt80 = sqrt64 X 16
Sqrt 64 X 16 = 8 sqrt16
Area = 8 sqrt16

Question 143532: Could you please help me with this problem, I think I have the right answer, I just want to make sure that it is.
Problem---Explain in words the steps you would follow to solve √(x- 6)= 5. Give the solution for x.
Here is my answer
Since you cannot separate the terms under the radical until the radical itself is eliminated, you will make the equations on both sides of the sign to the second power. Once this is done sqrtx-6 turns into x-6, and five turns into twenty-five. From here your will add six to both sides, and there is your answer, x=31.

Question 143787: For the following function, C computes a value, where if you add millions of dollars to the value, the result is the cost of implementing a city recycling project when x , as a percent (not its decimal equivalent), citizens participate.
a) Using this model, approximately what is the cost if 60% of the citizens participate?
Using this model, estimate the percentage of participation that can be expected if $5 million is spent on this recycling project? Set up an equation and solve algebraically. Round to the nearest whole percent.

Question 143788: For the following function, C computes a value, where if you add millions of dollars to the value, the result is the cost of implementing a city recycling project when x , as a percent (not its decimal equivalent), citizens participate.
FORMULA- C (x)= 1.5x / 100x
a) Using this model, approximately what is the cost if 60% of the citizens participate
Using this model, estimate the percentage of participation that can be expected if $5 million is spent on this recycling project? Set up an equation and solve algebraically. Round to the nearest whole percent.

Question 144246: 2x^2 – 12x + 18 divided by 2x^2 – 18
I need to simpliy this. The answer I have is: -12x + 18 divided by -18. Is this correct?
You can divide both by 2, giving
If you divide it, you get 1 with a remainder of -6x+18.
