Answer:
The answer to your question is the third choice 4 / (3d - 12)
Step-by-step explanation:
Data
length = (d -2 ) / (3d - 9)
width = 4/(d - 4)
height = (2d - 6)/(2d - 4)
Process
1.- Multiply the numerators
(d - 2)(4)(2d - 6) = 8(d - 2)(d - 3)
2.- Multiply the denominators
(3d - 9)(d - 4)(2d - 4) = 6(d - 2)(d - 4)(d - 3)
3.- Simplify
8(d - 2)(d - 3) / 6(d - 2)(d - 4)(d - 3)
8 / 6(d - 4)
Simplify 8/3 = 4/3
4/3(d - 4)
