Distributive and addition properties

Step-by-step explanation:

We are given that an expression

Which is equivalent to

The expression can be written as

Using distributive property

Now, using addition property of integers

We get

Hence, the option C is true.

1/5^2 = 7.56/45

if you are looking for the unit rate then the answer would be 9 because unit rate is distance divided by time.
