Answer:
455ways
Step-by-step explanation:
This is expressed as 15 C 3 ( C- combination)
The concept of combination is used when we talk about selection.
Now we are selecting 3 from a sample of 15
15 C 3 = 15! / (15-3)! 3! = 15 ×14×13×12!/12!×3×2
= 5 × 7 × 13 = 455ways
Answer:A line segment
Step-by-step explanation:
First of all, we need all logarithms to have the same base. So, we use the formula

To change the second term as follows:

Finally, using the property

we have

So, the equation becomes

We can now use the formula

to write the equation as

Now consider both sides as exponents of 2:

This equation has no "nice" solution, so I guess the problem is as simplifies as it can be
