Answer:

Step-by-step explanation:

Notice that x + 7 is a factor of the first two terms, and that it is also a factor of the last two terms. Thus,

x^3+7x^2-2x-14 = (x + 7)(x^2 - 2).

We could carry the factoring further, as follows:

(x + 7)(x^2 - 2) = (x + 7)(x - √2)(x + √2)

Which expression is equivalent to the following complex fraction?

True [87]

Answer:

Step-by-step explanation:

Given the complex fraction;

$-\frac{2}{x} +\frac{5}{y} / \frac{3}{y} - \frac{2}{x} \\$

First we will find the LCM of the numerator and the denominator as shown below;

$\frac{-2y+5x}{xy} /\frac{3x-2y}{xy}$

Then we divide both equation by multiplying the numerator by the reciprocal of the denominator as shown;

$= \frac{-2y+5x}{xy} * \frac{xy}{3x-2y} \\= \frac{-2y+5x}{3x-2y} \\$

This gives the required answer

How much work is done by a man who uses a force of 7 Newtons to push a box 3 meters across the room?

ElenaW [278]

The formula to calculate work done is -

Work done ( in joule, J) = Force (in Newton) X Distance (in meters)

So, we will use the formula to calculate work done,

Here, force is given as = 7 newtons

Distance is given as = 3 meters

So, work done will be -

Work done ( in joule, J) = 7 Newtons X 3 Meters

<u>Work done ( in joule, J) = 21 J (in joule)</u>
