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.
Answer:
Inequalities that use < or > symbols are plotted with a dashed line to show that the line is not included in the region. Inequalities that use ≤ or ≥ symbols are plotted with a solid line to show that the line is included in the region.
The simplified fraction is 1 6\14 One and six fourteenths or 1 2\7 one and two sevenths
With multiplication, there are a few handy rules to remember:
If you multiply an even and an even, the answer will be even!
If you multiply an odd and an odd, the answer will be odd!
If you multiply an even and an odd, the answer will be even!
Knowing this, if we go back and look at the numbers Evan is trying to multiply, we can try to use these rules!
The last number of that really big number is a 7, which is odd, and the number 2 is even, and because we know that an odd number times an even number is an even number, Evan will be right!
