Answer:

x = 6

Step-by-step explanation:

\frac{2}{3} x + 4 = 8 \\  \frac{2x}{3}  = 8 - 4 \\ \frac{2x}{3 }  = 4 \\ 2x = 4 \times 3 \\ 2x = 12 \\  x= 6

Answer:

x=6

Step-by-step explanation:

2/3x+4=8\\

<em>Subtract 4 from both sides</em>

2/3x=4

<em>Multiply both sides by 3</em>

6/3x=12\\2x=12

<em>Divide both sides by 2</em>

x=6

Answer:

\frac{4x^3-3x^2+5x+6}{x+6}=4x^2-27x+167-\frac{996}{x+6}

Step-by-step explanation:

The division problem given to us is (4x^3-3x^2+5x+6)\div (x+6).

To perform the synthetic division, we write out the coefficient of the polynomial. We set the linear factor to zero and solve for x, this becomes our divisor. That is x+6=0\implies x=-6.

We carry out the synthetic division as shown in the attachment.

The result of the synthetic division is 4   -27   167   -996

The first three terms are the coefficients of the quotient and the last term is the remainder.

Therefore the quotient is q(x)=4x^2-27x+167 and the remainder is r(x)=-996.

The dividend, the quotient and the divisor are written as

\frac{4x^3-3x^2+5x+6}{x+6}=4x^2-27x+167-\frac{996}{x+6}

The correct answer is A
