The senior class is taking a trip to an amusement park. they received a special deal where for every 3 tickets they purchased they received one free ticket. 3 tickets cost $53.25. the total purchase of tickets cost $1384.50. how many tickets did they receive?

the answer would be c

the absolute value function

perimeter = 10 +  √10  units

explanation:

first, we will need to get the length of each line using the distance formula which is as follows:

distance = 

1- length of ab:

ab =   = 5 units

2- length of ac

length of ac is the same as ab = 5 units

3- length of bc:

bc =   =  √10  units

now, we can get the perimeter by adding the side lengths as follows:

perimeter = 5 + 5 +  √10

perimeter = 10 +  √10  units

hope this : )
