Answer:

19)  ( \frac{-2}{5})^2 = \frac{4}{25}

20) -9^{2} = -81

21)  2^{4} = 16

Step-by-step explanation:

The only wrong ones are

19)  ( \frac{-2}{5})^2 = \frac{4}{25}

20) -9^{2} = -81 ... negative is not inside a parenthesis that's why it is still negative

21) you can add another way is 2^{4} = 16

Everything else looks good.  Great job!

How to write an equation and use The Distributive Property .
Airida [17]
<h2>Answer</h2>

Distributive Property

The distributive property states that when a factor is multiplied by the sum of two numbers, you can multiply each of the two numbers by that factor and then add them.

<h2>Example</h2><h3>Equation </h3>

10(x + 2) = 45

Apply the distributive property to the left side of the equation by multiplying

two numbers inside the parentheses by 10

10(x) + 10(2) = 45

Now add them

10x + 20 = 45

Rearrange the like terms

10x = 45 -20

10x = 25

x = 25/10

x = 2.5
