Answer:
2
Step-by-step explanation:
because whether a child or an adult buys the ticket it is still $9.50
It has to be 438 because any number that is 5 or higher must be rounded up so 438 could be rounded up to 440
It factors to (x+12)(x-12)
This is the same as (x-12)(x+12) as we can multiply two expressions in any order we want. This is like saying 7*5 is the same as 5*7
I used the difference of squares rule to factor x^2 - 144. It might help to write x^2 - 144 as x^2 - 12^2, then compare it to a^2 - b^2 = (a-b)(a+b)
