The answer is 4 square root 5 or -4 square root 5
Example A means
For every #of felt pieces you multiply that by the cost of one piece of felt to see how much you spent
Example
Felts cost $3 a piece
You get 7 pieces
7 x 3= 21
You spent $21 on felt

Radical Equation:
1. Isolate the radical expression.
2. Square both sides of the equation: If x = y then x2 = y2.
3. Once the radical is removed, solve for the unknown.
4. Check all answers.
Another way of saying it:
1. Isolate the radical expression involving the variable. ...
2. Raise both sides of the equation to the index of the radical.
3. If there is still a radical equation, repeat steps 1 and 2; otherwise, solve the resulting equation and check the answer in the original equation.
