Which statement about a dilation with a scale factor of 3 is true? a. three is added to each side in the pre-image to find the corresponding side length in the image. b. three is subtracted from each side in the pre-image to find the corresponding side length in the image. c. each side in the pre-image is multiplied by three to find the corresponding side length in the image. d. each side in the pre-image is divided by three to find the corresponding side length in the image.

The correct answer is C.

Step-by-step explanation:

A dilation is when you change the overall shape of a figure by a multiplicative.

If you dilate something by a factor of x, you're multiplying each side by x.

The answer is option C, "Each side in the pre-image is multiplied by three to find the corresponding side length in the image."

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
