15 ! the perimeter of a rectangle is 20 units. if the width is 3/4 of the length what is the width of the rectangle?

5 5/7 units

Step-by-step explanation:

Length = x

Width = 3/4 x

Perimeter = 20 units

2( x + 3/4 x) = 20

x + 3/4 x = 10

7/4 x = 10

x = 40/7 = 5 5/7 units

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 !
