Answer:

Step-by-step explanation:

Given:

(x+12y)/x=19

Simplifying:

x+ 12y = 19x
12y=18x
x/y = 2/3

Finding the value of:

(144x^2 +24xy + y^2) /y^2 =
144 (x/y)^2 + 24 (x/y) + 1 =

Substituting x/y with 2/3:

144 (2/3)^2 + 24 (2/3) + 1 =
144 (4/9) + 16 + 1 =
64 + 16 + 1 =

What is the width of a box when the length is x+2, the height is x+8, and the volume is x^3+9x^2+6x-16?

Nostrana [21]

(x+2)(x+8) = x^2 +10x +16

(x^2 + 10x + 16)(x-1) = x^3+9x^2+6x-16, so the other dimension is x-1
