X2 + 12 = 7x x2 – 7x + 12 = 0factor the equation (x – 3 ) ( x – 4 ) = 0 Then equating both factor to 0 X – 3 = 0 X = 3 And X – 4 = 0 X = 4 So the answer is X = 3 X =4
X2 - 8x + 15 = 0
(x - 3)(x - 5) = 0
critical points are at 3 and 5

Anyways here’s the answer:
160 cm squared.
You find volume by doing length x width x height and then take that answer and divide it by 3. When you do 8x6x10, 480, and 480 divided by 3 is 160.
