Aaron travels 3 miles per hour in still water on his kayak. The expression 3 can be used to find the time it takes for him to travel

with the current. If x represents the rate of the current, what does the denominator represent?

your answer would be 10x - 1

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72

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 : )
