The true statement about the Internet connection cost is D. Any amount of time over an hour and a half would cost $10.

<h3>How to explain the cost?</h3>

In this situation, the function is f (t), when t is a value between 0 and 30. The cost is $0 for the first 30 minutes

When t is a value between 30 and 90, the cost is US$ 5 if the connection takes between 30 and 90 minutes.

Here, the true statement about the Internet connection cost is D. Any amount of time over an hour and a half would cost $10.

Mrrafil [7]

Answer:

P=16+2x

Step-by-step explanation:

The formula for finding the perimeter of a rectangle is P=2l+2w.

Plug the length of 8 and the width of x into the formula.

You'll get P=2(8)+2(x).

Multiply. 2•8=16 and 2•x=2x.

Your expression is P=16+2x.

I hope this helps.
