Collect a minimum of 10 data points; you may use the internet to collect this data. construct a scatter plot of the data including the regression line as well as a residual plot.

7

step-by-step explanation:

the answer would be 7

step by step explanation: when u removing the parentheses and combined them that would be : x+3y-x-y=2y

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 : )
