We can break this down by removing the parenthesis first:
-2 + + 5 -
In order to continue, you have to simplify the square roots by factoring it and taking out i:
-2 + + 5 -
Combine like terms:
-3 - <-- that's the answer

Answer:
Part a) 3.5 weeks
Part b) 185 tickets
Step-by-step explanation:
Part a) After how much time have the same number of tickets been sold for both festivals?
Let
x -----> the number of weeks
y ----> the number of tickets sold
we have
<em>Country Music Festival</em>
----> equation A
<em>Pop Music Festival</em>
----> equation B
Equate equation A and equation B
solve for x
Part b) What is the number of tickets sold at that time?
substitute the value of x=3.5 weeks in the linear equation A or linear equation B
