denis-greek [22]

Answer:

Length 37 cm, width 25 cm.

Step-by-step explanation:

Let the original dimensions be length x and width x - 12 cms.

The new dimensions will be length (x - 2) and width (x - 12 - 2) = x-14 cm.

So , from the areas, we have:

x(x - 12) - (x - 2)(x - 14) = 120

x^2 - 12x  - (x^2 - 16x + 28) = 120

-12x + 16x - 28 = 120

4x = 148

x = 37 cms

So the length was 37 cm and the width was 37-12 = 25 cm.

Answer:

1). g(-9) = -81.914

2). Last option

Step-by-step explanation:

1). f(x) = x²

   For x = -9

   f(-9) = (-9)² = 81

   g(x) = \frac{32}{2x-17}

   g(-9) = \frac{32}{[2(-9)-17]}

           = \frac{32}{-35}

           = - \frac{32}{35}    

   (g - f)(-9) = g(-9) - f(-9)

                  = -\frac{32}{35}-81

                  = \frac{-32-2835}{35}

                  = -\frac{2867}{35}

                  = -81.914

2). The relation is not a function because this function doesn't passes a vertical line test.

Last option will be the answer.
