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."

I took the Unit Test on E d g e n u i t y and it was right.

Have a great day!! \(^u^\)

the fist one is not equalvalent but i think th second one isand the third isnt definetly or the last one is i think. hope this !

step-by-step explanation:

hello from mrbilldoesmath!

answer:   (7x + 6y) ( 49x^2 - 42xy + 36y^2)

discussion:

in general, the factorization of a^3 + b^3 is

a^3 + b^ 3 = (a + b) ( a^2 - ab + b^2)

in our case note that 343 = 7^3 and 216 = 6^3 so the equation becomes:

343x^3 + 216y^3 = (7x)^3 + (6y)^3

if you think of a (above) as 7x and b as 6y the factorization becomes

343x^3 + 216y^3 =

((7x + 6y) (   (7x)^2 - 7x*6y + (6y)^2)   =

(7x + 6y) ( 49x^2 - 42xy + 36y^2)

(a + b) (a^2 - a b + b^2)
