Answer:

$4(x + 3) + 2x = 6(x + 2)$
$5 + 2(3 + 2x) = x + 3(x + 1)$

Step-by-step explanation:

$5(x + 3) + x = 4(x + 3) + 3 \\ 5x + 15 + x = 4x + 12 + 3 \\ 5x + x - 4x = 12 + 3 - 15 \\ 2x = 0$

Divide both sides of the equation by 2

2x/2 = 0/2

x = 0

(4+612+x)=2(3x+8)

4+612+x=6x+16

4+612-16=6x-x

600=5x

Divide both sides of the equation by 5

600/5 = 5x

120 = x

Find the length of the unknown side. Round your answer to the nearest tenth.<br> 20 m<br> 12 m<br> b

stepladder [879]

The length of the unknown side is 16 meters

<h3>What is a right triangle?</h3>

A right triangle is a triangle that has one of its angles to be 90 degrees

The length of the unknown side is calculated using the following Pythagoras theorem.

$20^2 = 12^2 +b^2$

Evaluate the exponents

$400 = 144 +b^2$

Collect like terms

$b^2 = 400 -144$

Evaluate the like terms

$b^2 = 256$

Take the square root of both sides

$b = 16$

Hence, the length of the unknown side is 16 meters
