Answer:
10
Step-by-step explanation:
x is 10
Absolute value only removes the negative signs. Just multiply the numerator and the denominator
Answer:
x = 10
Explanation:
Note the following rules before we begin:
2 ln(a) = ln (a²)
ln (a) + ln (b) = ln (ab)
Now, for the given:
ln(20) + ln(5) = 2 ln(x)
ln(20*5) = ln(x²)
ln(100) = ln(x²)
This means that:
100 = x²
Therefore:
either x = 10 .........> acceped
or x = -10 .........> rejected as no negatives are allowed within ln functions
Hope this helps :)

Determine the part left
The part left is calculated using:
Take LCM
10 red marbles
Multiply the # of blue marbles by 2 (since there was TWICE as many red marbles), and you have your answer (above)
