. The volume of a box is 405 cubic units. The length is x units, the width 4 units greater than the length, and the height is 9

lukranit [14]

Answer:

length = 5

width = 9

Step-by-step explanation:

V = lwh

let 'x' = length

let '4+x' = width

9 = height

405 = 9x(4+x)

405 = 36x + 9x²

this is a quadratic equation: 9x² + 36x - 405 = 0

factor out a 9 to get:

9(x² + 4x - 45) = 0

9(x-5)(x+9) = 0

one root is 5 and the other is -9

since distance cannot be negative we use 5 as the length and 9 is the width

2a - 2 = a + 1

2a - a = 1+2

a = 3

XY = 3a - 4

= 3×3 - 4
