You want to find the sum of -3x2 + 7x-4 and -2 + 5x - x3. Which addition shows like terms lined up correctly?

0x³ - 3x² + 7x - 4

           +

               -x³ + 0x²  + 5x - 2

Step-by-step explanation:

4+4+2x

or

2x+8

step-by-step explanation:

it is rigid.; it is isometric. ; the size is preserved.

step-by-step explanation:

a translation is called an isometry; these are transformations that preserve congruence between pre-images and images.

they are also called rigid transformations, as the only thing that can happen to a pre-image is that it is moved or turned, not stretched or shrunk.

since congruence is preserved, the size is preserved.
