Area=l*b=l*(l-2)=80(given)

so, l^2 - 2l =80
   l^2 - 2l - 80=0
   l=10 or -8

l=10,b=10-2=8
perimeter=2(l+b)=2(18)=36

Answer:

D) It is doubled

Step-by-step explanation:

Regardless of the side length, if the area of a square is quadrupled, the side lengths get doubled, as shown in the diagram. If all of the side lengths are doubled, that means the perimeter is also doubled.

5x+21+178/(x-7)<br> How do I solve for domain and range on this equation?
Luda [366]
The domain is easiest. You simply need to find the fractions, and exclude any X that makes the denominator zero. So in this case, your domain is everything except X=7.

For range, you are trying to find out what are the possible answers. Usually the best way to do this is to try x=infinity, and x=negative infinity, which here gives you answers of infinity and negative infinity. Since the function is almost continuous, I think your range is any real number.
