In order to evaluate the radical, we will need to multiply 8 by 3 to get 24. Now find the common factors of 24 I will use 6 and 4.

You can now use 6 radical 4.

Calculate the force on an area of 16 m2, if the pressure applied is 50 Pa
Andre45 [30]

Pressure is simply the ratio of force over area. In formula this is written as:

Pressure = Force / Area

 

So calculating for the force:

Force = Pressure * Area

Force = 50 Pa * 16 m^2

<span>Force = 800 N</span>

√(2x-5)=1+√(x-3)
Ostrovityanka [42]

Answer:

x = 3 only

Step-by-step explanation:

\sqrt{2x-5} =1+\sqrt{x-3}

\implies 2x-5=(1+\sqrt{x-3})^2\\\\ \implies 2x-5=x+2\sqrt{x-3} -2

\implies x-3=2\sqrt{x-3}

\implies (x-3)^2=(2\sqrt{x-3})^2

\implies x^2-6x+9=4x-12

\implies x^2-10x+21=0

\implies (x-3)(x-7)=0

\implies x=3, x=7

Check by substituting found values of x into original equation:

x=3 \implies \sqrt{2(3)-5} =1+\sqrt{3-3} \implies 1 = 1 \ \ \ \checkmark

x=7 \implies \sqrt{2(7)-5} =1+\sqrt{7-3} \implies 3\neq  2 \ \ \ \ incorrect
