Answer:

30 seconds

Step-by-step explanation:

Find the least common multiple of 6 and 15.

First, write the prime factorizations.

6 = 2 × 3

15 = 3 × 5

The LCM is the product of each distinct factor.

LCM = 2 × 3 × 5

LCM = 30

They flash together at the same time every 30 seconds.

Which expression is equivalent to log3(x + 4)?
dangina [55]

Answer:

log[3(x+4)] is equal to log(3) + log(x + 4), which corresponds to choice number three.

Step-by-step explanation:

By the logarithm product rule, for two nonzero numbers a and b,

\log{(a \cdot b)} = \log{(a)} + \log{(b)}.

Keep in mind that a logarithm can be split into two only if the logarithm contains the product or quotient of two numbers.

For example, 3(x + 4) is the number in the logarithm \log{[3(x + 4)]}. Since 3(x + 4) is a product of the two numbers 3 and (x + 4), the logarithm \log{[3(x + 4)]} can be split into two. By the logarithm product rule,

\log{[3(x + 4)]} = \log{(3)} + \log{(x + 4)}.

However, \log{(x + 4)} cannot be split into two since the number inside of it is a sum rather than a product. Hence choice number three is the answer to this question.
