I'm assuming the limit is supposed to be

Multiply the numerator by its conjugate, and do the same with the denominator:

so that in the limit, we have

Factorize the first term in the denominator as

The
terms cancel, leaving you with

and the limand is continuous at
, so we can substitute it to find the limit has a value of -1/18.
48 degrees, anything opposite of a degree on the same 2 infinite lines will always be the degree.
First, Jane must know the volume of the box.
Volume = l * w * h
Volume = 1 * 0.5 * 0.5
Volume = 0.25 yard^3
1 yard^3 = $25
So,
1 : 25 = 0.25 : x
x = 25 * 0.25
x = $6.25
So she need to spend $6.25
no because she turned it only 90 degrees not 180.
180 would be a mirror reflection
