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
If you would like to write y - x - 1 = 0 in the general form, you can do this using the following steps:
The general form of the equation is: ax + by + c = 0.
y - x - 1 = 0
-x - y - 1 = 0
The correct result would be <span>-x - y - 1 = 0</span>.
