How to get everything to one side of the inequality for 3+4/x>=(x+2)/x
Ksenya-84 [330]

Answer:

2x+2\geq 0

Step-by-step explanation:

Given:

The given inequality is.

3+\frac{4}{x} \geq \frac{x+2}{x}

Solution:

Simplify the given expression.

3+\frac{4}{x} \geq \frac{x+2}{x}

Multiply by x both side of the equation.

x(3+\frac{4}{x}) \geq x(\frac{x+2}{x})

Simplify.

3x+\frac{4x}{x} \geq x(\frac{x+2}{x})

3x+4\geq x+2

Rewrite the equation as.

3x+4-x-2\geq 0

2x+2\geq 0

Therefore, 2x+2\geq 0 is the simplest form of the given expression.

Answer:

Its 9.0 units

Step-by-step explanation:

For the side mostly to the left, its gonna be 3 units, since we can easlily count it

Now, for the diagonals, we have to use the formula for the area of a triangle, which is (l * w) / 2 = a.

For the bottom side, its 3 along the x axis and 1 along the y axis. 3 * 1 is 3, now divide that by 2 and you got 1.5

Now, for the right side, its 5 on the y, 1 on the x. Multiply 1 by 5, you got 5. Now divide that by 2 and you have 2.5

Finally, for the top side, its 4 on the x, and 1 on the y. 4 * 1 is 4, divided by 2 and its 2.

Alright, now we have to add 'em all together. 3 + 1.5 + 2.5 + 2 is 9 units

Theres your answer :)
