Answer:

Hence, the values of x for which the expression is not defined is equal to 1 or -1.

Step-by-step explanation:

We are asked to find for which values of x is the rational expression:

\dfrac{x+5}{3x^2-3} is undefined.

We know that a rational expression is undefined when the denominator term is equal to zero.

Hence, we could represent the algebraic expression as:

\dfrac{x+5}{3x^2-3}=\dfrac{x+5}{3(x^2-1)}\\\\\dfrac{x+5}{3x^2-3}=\dfrac{x+5}{3(x-1)(x+1)}

Hence, clearly from the expression we could observe that:

the expression is not defined when x=1 or x=-1.

( since the denominator will be zero if x receives any of the above two values or both)

Hence, the values of x for which the expression is not defined is equal to 1 or -1.

You find the following financial information about a company: net working capital = $735; fixed assets = $5,385; total assets =
ddd [48]

Answer:

Company's total liabilities are $6,351.

Step-by-step explanation:

A company's financial information is given, we have to calculate the company's total liabilities.

Total assets = Fixed assets + current assets

Current assets = Total assets - Fixed assets

                         = $8,190 - $5,385

                         = $2,805

Networking capital = Current assets - Current liabilities

                        $735 = $2,805 - current liabilities

  Current liabilities   = $2,805 - $735

  Current liabilities   = $2,070

Total liabilities = Long term debt + current liabilities

                         = $4,281 + $2,070

                         = $6,351

Company's total liabilities are $6,351.
