Step-by-step explanation:
You need to use the following Properties of Logarithms:

Given the following expression:

You can follow these steps in order to write it as a single logarightm:
- Apply the first property shown above:

- Apply the second property:

- Finally, apply the third property:

5*4*6=120
4+(6+9)=19
675+9=75
<span>6 yr 7 months+ 2 yr 11 months = ?
6 yr + 2 yr = 8 yr
7 months + 11 months = 18 months = 1 yr 6 months
8 yr + </span>1 yr 6 months = 9 yr 6 months
answer is C<span>. 9 yr 6 months</span>
Answer:
1120°
Step-by-step explanation:
Use the sum of interior angles formula:

Where n is the number of sides.
In a nonagon, there are 9 sides, substitute 9 for n:

Since our nonagon is a regular nonagon, all 9 angles measure the same, so each angle measures:

Subtract 140 from 1260:
