The graph shows a function and its reflection over the X axis. Which equation describes the function? A. y = (x)^2 + 6
B. y = (x - 3)^2
C. y = (x + 3)^2 - 9
D. y = (x + 2)^2 - 25

180° is the answer from the equation

Volume is length times width times height so
20 times 8 times 30 which is 4,800
surface area is ph (p is perimeter of base), h is height.
so perimeter would be length+length+width+width so 20+20+8+8 which is 56. so multiply 56 times 30 which is 1680. hope this !
