Two sailboats are traveling along the same path away from a dock, beginning from different locations at the same time johns boat begins 25 miles from the dock and is 55 miles from the dock after 5 hours. The distance of Roberta's boat from the dock is represented by the function y=5x+30 where x represents time and y represents the distance from the dock

i hope that is right.

step-by-step explanation:

this is a good question! i’ll do some research and what i find, i’ll contact you asap when i have something! ✊

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 : )
