Answer:

\huge{ \fbox{ \tt{12}}}

Step-by-step explanation:

\underline{ \sf{Given}} : \sf a=6, \:  b=3 \:  and  \: c=2

\underline{ \sf{To \: find }}  :   \sf{Value \: of \: the \: given \: expression}

\underline{ \underline{ \mathfrak{Let's \: solve}}} :

\bigstar{ \tt{ \: c \: ( \: b \:  +  \: a \: ) -  \: a}}

\text{Step \: 1 \: } : Plug the values of a , b and c

\mapsto{ \tt{ \: 2 \: ( \: 3 \:  +  \: 6 \: ) \:  -  \: 6}}

\text{Step \: 2} : \sf{ \: Add \: the \: numbers : 6 \: and \: 3}

\mapsto{ \sf{ \: 2 \: * \: 9 \:  -  \: 6 \: }}

\text{Step \: 3 \: } : \sf{ \: Multiply \: the \: numbers : 9 \: and \: 2}

\mapsto{ \sf{18 - 6}}

\text{Step \: 4 \:} :  \sf{Subtract \: 6 \: from \: 18}

\mapsto{ \sf{ \: 12}}

Note : Just follow the PEMDAS rule ( See attached picture )

Hope I helped!

Best regards! :D

Which of the following is an extraneous solution of (45-3x)^1/2=x-9?
Iteru [2.4K]

Answer:

C. x =3

Step-by-step explanation:

Extraneous solution is that root of a transformed equation that doesn't satisfy the equation in it's original form because it was excluded from the domain of the original equation.

Let's solve the equation first

\sqrt{45-3x} = x-9\\Taking\ square\ on\ both\ sides\\{(\sqrt{45-3x})}^2 = {(x-9)}^2\\45-3x = x^2-18x+81\\0 = x^2-18x+81-45+3x\\x^2-15x+36 = 0\\x^2-12x-3x+36 = 0\\x(x-12)-3(x-12) = 0\\(x-3)(x-12)\\x-3 = 0\\=> x =3\\x-12 = 0\\x = 12\\We\ will\ check\ the\ solutions\ one\ by\ one\\So,\\for\ x=3\\\sqrt{45-3(3)} = 3-9\\\sqrt{45-9} = -6\\\sqrt{36}= -6\\6\neq -6\\For x=12\\\sqrt{45-3(12)} = 12-9\\\sqrt{45-36} = 6\\\sqrt{36}= 6\\6=6

Hence, we can conclude that x=3 is an extraneous solution of the equation ..

2x + 2x + 2 = 4x + 2<br> Do this equation has one solution,many solutions,or no solutions?
Slav-nsk [51]

Step-by-step explanation:

2x + 2x + 2 = 4x + 2           <em>combine like terms</em>

4x + 2 = 4x + 2          <em>subtract 4x from both sides</em>

4x - 4x + 2 = 4x - 4x + 2

2 = 2   TRUE

<h2>CONCLUSION:</h2><h3>This equation has an infinitely many solutions. The solution to this equation is any real number.</h3>
