Answer:

Perimeter 182 cm, area= 2,028 cm2

Step-by-step explanation:

The perimeter of the given rectangle is

  2(6 cm + 8 cm) = 28 cm

The area of the given rectangle is

  (6 cm)*(8 cm) = 48 cm^2

The larger rectangle will have a perimeter of

  6.5*28 cm = 182 cm

The larger rectangle will have an area of

  6.5^2*48 cm^2 = 2028 cm^2 . . . . . note the scale factor is squared for area

The appropriate choice is the 3rd one, ...

  Perimeter = 182 cm, area = 2,028 cm^2

What is an extraneous solution to the equation b/b-3 -5/b=3/b-3 ?
storchak [24]
\frac{b}{b-3} - \frac{5}{b} = \frac{3}{b-3}  \\   \frac{ b^{2} -5(b-3)}{b(b-3)} =\frac{b}{b-3} \\  \frac{ b^{2} -5b+15}{b^2-3b} =\frac{b}{b-3} \\ (b-3)(b^{2} -5b+15)=b(b^2-3b) \\ b^3-8b^2+30b-45=b^3-3b^2 \\ 5b^2-30b+45=0 \\ b^2-6b+9=0 \\ (b -3)(b-3)=0 \\ b=3

To check: 3/3-3 - 5/3 = 3/0 - 5/3 which is not defined.

Therefore, b = 3 is an extraneous solution.
