An exponential function is written as Flx) = a. by where the coefficient a is
the base bis positive but not equal to 1, and the exponent xis any
number

my guess would be b and d, but i didn’t actually get out the pen and paper. lol

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 : )

parallel lines have the same slope. so if the green line has a slope of -4, the slope of the red line is also -4.
