Answer:

p - 4

Step-by-step explanation:

Prime number is a number that only has 2 factors, 1 and the number itself. Therefore, multiplying p by 2 or 7 means giving the number more than 2 factors, which would make the number no longer prime. Squaring the prime number itself does the same.

Let p = 7.

2p = 2*7 = 14                  14 = 1*2*7*14

7p = 7*7 = 49                 49 = 1*7*49

p - 4 = 7 - 4 = 3              3 = 1*3

p^2 = 7^2 = 49               49 = 1*7*49

Which graph shows a dilation?
dimulka [17.4K]

Answer:

The third one.

Explanation:

A dilation is a shrink or a stretch of a figure.  

In a dilation, all sides either increase or decrease by the same scale factor.  Additionally, in a dilation the angle measures of the figure do not change.

In the first figure, we can see that the base angles of the pre-image are slightly different than those of the image.  This is not a dilation.

In the second figure, the angles are noticeably different; again, not a dilation.

In the fourth figure, much like the second figure, the angles are noticeably different.  This is not a dilation.

In the third figure, however, we can see that the slanted sides of the larger figure go through three boxes; they are three units long.  Additionally we can see that the slanted sides of the smaller figure go through 1 side; this is a dilation b a factor of 3.  

The base sides of the third figure, in the larger shape, are 6 units long; in the smaller figure, they are 2 units long.  This is a dilation by a factor of 3.
