I love u

Dilation =  was done on a rectangle.

→As Factor of Dilation is 0.4, which is less than 1.

→So, the image will be smaller in size than Pre image.

→As, the two rectangles , Pre image and image are similar so their sides will be proportional.

As in similar figures the interior angles are congruent.

As the images are similar , so Base of the image will be two fifths of the size of the base of preimage.

Option A,B and E are Correct.

A: The image is a reduction because n < 1.

B : The side lengths of the image are two-fifths the size of the corresponding side lengths of the pre-image.

E. The base of the image is two-fifths the size of the base of the pre-iDilation =  was done on a rectangle.

→As Factor of Dilation is 0.4, which is less than 1.

→So, the image will be smaller in size than Pre image.

→As, the two rectangles , Pre image and image are similar so their sides will be proportional.

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9

just keep asking questions until you have a better understanding.
