Help plz I need the answers and the steps someoneee responddd

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.

we need to divide the number of toy dinosaurs, 156, by the number of brothers, 4:

in order to estimate, we can use compatible numbers:

156 ÷ 4

  ↓

160   ÷ 4 = 40        

the correct answer is a).

16 b

17 d

step-by-step explanation:

16.

amount = 3250(1.06) ^3.5 = 3985.23

17.

m = 9pn

divide both sides by 9n: -

p = m/9n
