Actually, the area of the square is 49 cm^2.

The length of one side is sqrt(49 cm^2) = 7 cm (answer)

19. Luggage on a certain airline is limited to 2 pieces per person.

Mama L [17]

Answer: The second piece can weigh 256 pounds at most.

Step-by-step explanation:

Hi, to answer this question we have to write an inequality with the information given:

The sum of the weight of each piece of Luggage must be less or equal to 581 pounds:

x + 325 ≤581

Where x is the second piece's weight.

Solving for x:

x ≤581 -325

x ≤ 256

The second piece can weigh 256 pounds at most.

How do you simplify this?

timama [110]

Notice how the top is an addition of two cubes, namely x and 2.

You can rewrite the equation as:

$\frac{x^{3} + 2^{3}}{x + 2}$

Now, (a + b)³ can be simplified down to (a + b)(a² - ab + b²)
Following the same pattern, we get:

$\frac{(x + 2)(x^{2} - 2x + 4)}{x + 2}$
$= x^{2} - 2x + 4$

Answer: See below.

Step-by-step explanation:

Let's go number by number.

Rational pretty much means you can put it into a fraction of whole numbers.

The first number is -81,572.

This number is rational because it can be put into a fraction ( $\frac{-81572}{1}$ ) that is made up of whole numbers.

The second number is $\sqrt{11}$ .

This number is irrational because it cannot be put into a fraction of whole numbers.
Keep in mind that most squareroots are irrational. Especially those that don't equal a whole number.

The third number is 5.636336333
