Alice is building a fenced in pen in her backyard for her dog, as shown. write an expression that represents the total amount of fencing she will need in feet. if the longer dimensions of the rectangle is 27 feet how many feet of fencing does Alice need?

p = 2 * w + 54

Step-by-step explanation:

To know the number of feet Alice needs, you must calculate the perimeter, the perimeter of a rectangle would be the sum of its sides, that is, twice the width and twice the length.

This time they give us the length that is equal to 27 feet, therefore, the equation of the perimeter would be:

p = 2 * w + 2 * l

p = 2 * w + 2 * 27

p = 2 * w + 54

Therefore, to know exactly what Alice needs, you need to know the value of the width and shortest side.

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.

compare the two slopes in the decimal form. if the slopes are equal, then the lines are parallel. if the slopes are not equal, then the lines are not parallel.
