The combined land area of the countries a and b is 177 ,973 square kilometers. country a is larger by 773 square kilometers. det

Troyanec [42]

Let b = x

a = x + 773

x + x + 773 = 177973

2x + 773 = 177973

2x = 177973 - 773

2x = 177200

x = 177200/2

x = 88600

The other is x + 773, = 88600 + 773 = 89373

Each country is 88600 and 89373 square kilometers.

Simplify -14x^3/x^3- 5x^4 where x=?

ki77a [65]

Step-by-step explanation:

$\dfrac{-14x^3}{x^3-5x^4}\qquad\text{where}\ x^3-5x^4\neq0\\\\x^3-5x^4\neq0\qquad\text{distributive}\\\\x^3(1-5x)\neq0\iff x^3\neq0\ \wedge\ 1-5x\neq0\\\\x\neq0\ \wedge\ x\neq\dfrac{1}{5}\\\\\dfrac{-14x^3}{x^3(1-5x)}\qquad\text{cancel}\ x^3\\\\=\dfrac{-14}{1-5x}\qquad\text{where}\ x\neq\dfrac{1}{5}$
