(2 - 5x) por (5 + 3x)

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72

this is a good question! i’ll do some research and what i find, i’ll contact you asap when i have something! ✊

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.
