Well i tried 72 = (x+4)(x+1)(x+2) and i subbed in 2, and it worked out.

ohhh or is it 72=(x)(2x)(4x)?

Thanks :) Can you please help me with this question :) Maria designed a rectangular storage unit with dimensions 1m by 2m by 4m. By what shoulds he increase each dimension to produce an actual storage that is 9 times the volume of his scale model? v= (1) (2) (4) v= 8 v has to be 9 times...

or (x+1)(x+2)^2(x+4)^4

expand (x+2)(x+4)(x+1)?

expand the function?

I'm not sure, change the values of (x+1)(x+2)(x+4)

So the final volume is 134217728? or do you just do 8*9?

Do you do 8^9?
