90. Add the zero in front of the 9.
3 : 3 times 6 is 18, 2 times 9 is 18 and 3 times 3 is 9 plus 9 is 18
(9x-2) - (5x+6) =
4x-8 , this is your profit function
Rooms are 3 dimentional
they have volume
area times height=volume
if dimentions are the same, that means that the legnth, width, height are same, so therefor they have same area (Judy is correct)
if area area same, then the height could be different, so Mrs. Ferguson is wrong
Judy is correct and Mrs. Ferguson is wrong
