Simplify sqrt(x^2-16)

1 answer:

4 0

Remember for this type of question.I'm guessing you make the equation equal to 0. Then square both sides the (X ^2-16) and 0. Then the square root goes away. Then you factor it according to the difference of squares method. By taking the square root of x^2 and 16. So ultimately it turns into 2 binomials according to the difference of squares method. The simplified answer would be (X-4)(X+4)=0. To solve for x in each case, take each respective equation separately and make it equal to 0. Solve for x.

First, let's calculate the actual cost.
$239*6=1434$ is the actual cost of six nights.
The formula for percent error is $|\frac{measured value-accepted value}{accepted value}|*100$
The bars (|) stand for absolute value which gets rid of the negative sign if there is one.
Plug in the values: $|\frac{1434-1450}{1450}|*100$
 $|\frac{-16}{1450}|*100$
 $|-0.0110344828|*100$
 $0.0110344828*100$ 
 $1.10344828%$ is the percent error.

Step-by-step explanation:

Some nasty order of operations coming up.

Firstly, deal with that squared:

-12 / 3 * (-8 + 16 - 6) + 2

Simplify the bracket:

-12 / 3 * 2 + 2

Simplify -12 / 3:

-4 * 2 + 2

Simplify -4 * 2:

-8 + 2

Simplify:

-6
