Answer:

A traditional economy is a system that relies on customs, history, and time-honored beliefs. Tradition guides economic decisions such as production and distribution. Societies with traditional economies depend on agriculture, fishing, hunting, gathering, or some combination of them. They use barter instead of money.

Factorise x ^ 4 + 1/x ^ 4 - 3

kondaur [170]

Answer:

Step-by-step explanation:

Add 1 and subtract 1, so that the expression won't change.

$x^{4}+\frac{1}{x^{4}}-3=x^{4}+\frac{1}{x^{4}}-3 +1 - 1\\\\=x^{4}+\frac{1}{x^{4}} - 2 + 1\\\\= (x^{2})^{2} + (\frac{1}{x^{2}})^{2}- 2 *x^{2}*\frac{1}{x^{2}} - 1\\\\$

$= (x^{2} -\frac{1}{x^{2}})^{2} - 1\\\\=(x^{2}-\frac{1}{x^{2}})^{2}- 1^{2}$

(a² - b²) = (a+b)(a - b)

Here a = x² - (1/x²) and b = 1

$= [ (x^{2}-\frac{1}{x^{2}})+ 1 ] [ (x^{2} -\frac{1}{x^{2}} - 1 ]$

If the cost to purchase and install carpet is $4 per square foot, how much will it cost to put carpet in the family room and hal

andrey2020 [161]

The first step is to section the given daigram. It would be shown in the diagram below

Looking at the diagram,

Area of family room = 5.5 * 24 = 132 square feet

Area of hallway = 15.5 * 4 = 62 square feet

Total area to be covered with carpet is

132 + 62 = 194 square feet

Since the cost per square foot is $4, then the cost of putting carpet in the family room and hallway is

194 * 4 = $776* 4 = $776
