Fala wants to purchase a video game system that costs $309. She earns $12 for each hour that she works at her
father's hardware store. How many hours will Fala need to
work to earn enough money to purchase the video game
system?

26 hours or 25 hours and 45 min

Step-by-step explanation:

309/12= 25.75

multiplication is multiplication.   it might feel harder depending on what level of math you are in, but generally it will be the same old stuff, while implementing some new concepts and methods of solving work.

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 : )
