List the coordinates of the original figure and the new figure. Then determine the scale factor of the dilation. (I already did the original figure coordinates)

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length

v = 1/3 a^2h

step-by-step explanation:

the volume is 1/3 a^2h.

12r - 8 - 12

you have to combine like terms. below i have bolded the like terms:

12r - 8 - 12

together it combines to:

12r - 20

hope this !
