Anna wants to put a fence around a rectangular garden plot that measures 9 feet by
18 feet. she wants to place posts at the corners of the plot and every 2 feet around
the perimeter of the plot. how many posts does she need?

The answer is:

Anna will need 27 posts.

To calculate how many post does she need to place at the corners and every 2 feet around, we need to calculate the perimeter of the garden plot.

So, we can calculate the perimeter of the garden plot (rectangle) using the following formula:

We know that:

Then, calculating the perimeter of the garden plot, we have:

Now, calculating how many post she will need, we have:

Hence, we have that Anna will need 27 posts.

it is not that hard all u have to do is plot the graph

step-by-step explanation:

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
