the inequality simplifies to 3/x+2+1>0. which inequality is equivalent? a. 4/x+2>0 b. 4/x+2<0 c. x+5/x+2>0 d. x+5/x+
arsen [322]

Answer:

x \geqslant  - 5

Step-by-step explanation:

first subtract 1 from both sides of inequality then multiply both sides with x+2 and lastly leave x alone by subtracting 3 from boths sides and add x to both sides\frac{3}{x + 2}  + 1 \geqslant 0 \\  \frac{3}{x + 2}  \geqslant  - 1 \\ 3 \geqslant  ( - 1) \times (x + 2) \\ 3 \geqslant  - x - 2 \\ x \geqslant  - 5

The diagram below shows the rectangle BOAR B Find the length o fsegment PA . if entering your answer as a decimal, round your fi
yulyashka [42]

Answer:

4.62 units

Step-by-step explanation:

Let's first find the length OR.

OR² = BR² + OB²

OR² = 5² + 12²

OR² = 25 + 144

OR² = 169

OR = \sqrt{19}

OR = 13

Let's find the area of triangle OBR.

Using the formula :

½bh

Where

b = BR

h = OB

Therefore, area of triangle OBR =

½ * BR * OB

= ½ * 5 * 12

= 30

From the diagram, triange OBR and OAR are parallel to each other, and they equal.

Thus, area of OBR = area of OAR

To find the length PA, we have :

Area of OAR = ½ * OR *PA

Let's make PA subject of the formula:

PA = \frac{area of OAR}{\frac{1}{2} * OR}

PA = \frac{30}{\frac{1}{2} * 13}

PA = 4.618 ≈ 4.62

PA = 4.62 units
