Answer:

x=-5

Step-by-step explanation:

first you use distributive property:

3(2x+4)=-18

6x+12=-18

then you subtract your 12 from the -18

when you do that since you have 2 negatives you add

6x=-30

divide 6 by -30

x=-5

1/(x-2)+1/(x+3)=1/5 solve the problem for me

<h3>Final value : x² -9x - 11</h3>

════════════════════

$\frac{1}{(x - 2)} + \frac{1}{(x + 3)} = \frac{1}{5}$

$\frac{(x + 3) + (x - 2)}{(x - 2)(x + 3)} = \frac{1}{5}$

$\frac{2x + 1}{ {x}^{2} + 3x - 2x - 6 } = \frac{1}{5}$

$\frac{2x + 1}{ {x}^{2} + x - 6} = \frac{1}{5}$

2x + 1 = ⅕ × (x² + x - 6)

2x + 1 = ⅕x² + ⅕x - 6/5

1/5x² +1/5x - 2x - 6/5 - 1 = 0

1/5x² -9/5x - 11/5 = 0

x² - 9x - 11 = 0. #times by 5

a boat is traveling east across a river that is 112 meters wide at 8 meters per second. if the river has a northwest current of

OLEGan [10]

<h3>given:</h3>

boat speed= 8 m/s

river current= 5 m/s

the resultant speed of the motorboat rounded to the nearest 10.

<h3>solution:</h3>

use pythagorean theorem.

let the unknown be "x".

${a}^{2} = {b}^{2} + {c}^{2}$

${c}^{2} = \sqrt{ {a}^{2} + {b}^{2} }$

$x = \sqrt{ {8}^{2} + {5}^{2} }$

$x = \sqrt{64 + 25}$

$x = 9.4 \: m |s$

<u>hence</u><u>,</u><u> </u><u>the resultant speed of the </u><u>motorboat</u><u> </u><u>is</u><u> </u><u>9.4</u><u> </u><u>m</u><u>/</u><u>s</u>
