Answer:

3.4 meters.

Step-by-step explanation:

There are 100 centimeters in 1 meter:

<em>1 meter (m) = 100 centimeters (cm). </em>

You are given 3 m + 40 cm, and you want to convert to meter. In this case, divide 40 cm with the total centimeters to meter to obtain the meters.

40cm/100cm = 4/10 meters per centimeters.

Now, add that to the extra meters given.

3 meter 40 cm to meters = 3.4 meters.

2) √x+4=√(5x+4);

3) the 'x' can be calculated if to solve this equation:

$\sqrt{x} +4=\sqrt{5x+4}$ ;

$x+16+8\sqrt{x} =5x+4;$

$4x-12=8\sqrt{x} ;\ => \ x-2\sqrt{x} -3=0;$

$\left \{ {{\sqrt{x} =-1} \atop {\sqrt{x} =3}} \right. \ => \ x=9.$

4) finally, answer: 9.
