If f(x) = x^2-2x-24 and g(x) = x^2-x-30, find (f-g)(x).

Step-by-step explanation:

(f-g)(x) = x² - 2x - 24 - (x² -x -30)

           = x² - 2x - 24 -x² + x + 30

          =  x² - x² -2x + x - 24 + 30

          =  -x + 6

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 : )
