2 ln 8 + 2 ln y
The first thing we could do is use the distributive property and "take out" the 2.
After we do that, we get
2( ln 8 + ln y)
Here's a cool property of logarithms of any base.
log a + log b = log ab
Note: The bases of the logarithms must be the same for this to work.
Let's apply that property
2 (ln 8 + ln y)
= 2 ln 8y
That could be your answer. If you want to remove the 2, we can use the following property:
a log b = log (a^b)
2 ln (8y)
= ln (8y)^2
= ln (64y^2)
That could be another answer.
Have an awesome day! :)

Answer:
<em>~ Jill needs a minimum score of 90% to recieve an average of at least 92% on all her math quizzes ~</em>
Step-by-step explanation:
1. The table shows that her past weeks math quiz scores are: 92, 96, 94, 88
2. If she were to get a mean, or average, of at least 92, we could set up an equation to determine the minimum score she will recieve on her next quiz:
92 + 96 + 94 + 88 + x/ 5 = 92 ⇒ <em>(where x is the minimum score she should recieve on her next quiz to get an average of at least 92%)</em>
3. Now let us solve this equation for x through simple algebra ⇒
92 + 96 + 94 + 88 + x/ 5 = 92 ⇒
370 + x/5 = 92 ⇒
x/5 + 74 = 92 ⇒
x/5 = 18
x = 90
4. <em>Jill needs a minimum score of 90% to recieve an average of at least 92% on all her math quizzes</em>
Remember:
A triangle is always 180 degrees and so is a straight line so 360 degrees in total:
1) Add 92 and 123 which equals 215
Then 360 subtracted by 215 is 145
Answer: 145
2) add 100 and 25= 125
360-125= 235
Answer: 235 degrees
