The perimeter of a rectangle is 230 feet. the short sides are each 30 feet long, but the lengths of the long sides are unknown. which equation represents this situation?
30+2a=230
2(30)+2a=230
2(30)a=230
30a=230

For this case we have that by definition, the perimeter of a rectangle is given by:

Where:

a: It is the length of the rectangle

b: It is the width of the rectangle

We have as data that:

Then, replacing we have:

Option B

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.

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 !
