Which choice is equivalent to the expression below?
Phantasy [73]
Hello! The answer should be B: 6i\sqrt{6 . Since the square root is above a negative, an imaginary number would come out. Because of this, you can easily recognize that it would be B. 
However, if you can't, you could use the calculator to check (ignoring the negatives), 6\sqrt{6 is equal to \sqrt{216}. 
The final answer should be B.

Amount: 20$

Step-by-step explanation:

<u>Equation for Benito:</u>

<u>Equation for Tavon:</u>

  • 15 + x*0.5

<u>Since the sums equalize at some time, we get:</u>

  • 10+x= 15 +0.5x
  • x - 05x = 15- 10
  • 0.5x = 5
  • x= 5/0.5
  • x= 10 days

After 10 days, Juan will owe both Benito and Tavon $20
