If you know that log5 (2) - log5 (12) = 0, which of the following is false?

1 answer:

8 0

Answer:

Step-by-step explanation:

A is correct because $log_5(12)$ was added on both sides, which is supported by the Additive Property of Equality

C is correct because the Quotient Property of Logarithms states that $log_bM-log_bN=log_b(\frac{M}{N} )$

so $log_5(x)-log_5(12)=log_5(\frac{x}{12} )$ is correct

D is correct because using the fact that $log_5x=log_512$ it is easy to figure out that x=12

For B, there is no property supporting that statement.

It would be 10m.
If you divide 25 by 2.5 you get 10, and since we’re using velocity, that’s what we would do.

Answer:

After using distributive property to remove the parentheses $10(u-2)$ we get $10u-20$

Step-by-step explanation:

We need to use distributive property to remove the parentheses 10(u-2)

According to distributive property of multiplication over subtraction: $a(b-c)=ab-ac$

Using the above distributive property to solve the question. Multiply 10 with terms inside the bracket and solving:

$10(u-2)\\=10u-10*2\\=10u-20$

So, After using distributive property to remove the parentheses $10(u-2)$ we get $10u-20$
