What is the perimeter of aeb?

16.4 ft
18.5 ft
18.7 ft
22.9 ft

Hence, perimeter of ΔAEB is:

18.5 ft.

Step-by-step explanation:

The perimeter of ΔAEB is given as:

length of side AE+length of side BE+length of side AB.

As side AB║DF hence we will use Triangle Proportionality theorem to calculate the length of side AE.

Since,

Hence, we have:

Hence, perimeter of ΔAEB is:

6.5+4.2+7.8=18.5 ft.  

( since AE=6.5 ft

BE=7.8 ft

and AB=4.2 ft )

Hence, perimeter of ΔAEB is:

18.5 ft.

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.

hope i !

so, converting firstly the mixed fractions to improper fractions and then "adding".
