\text{Scale factor}=\frac{OB'}{OB}

4=\frac{OB'}{\frac{3}{4}}

4\times \frac{3}{4}=OB'

3=OB'

The length of OB' is 3 units. Therefore the correct option is option is B.

Answer:

(x - 2)

Step-by-step explanation:

Given expression is,

\frac{x^3+3x^2-4x-12}{x^2+5x+6}

We have to find the quotient.

x² + 5x + 6) x³ + 3x² - 4x - 12(x - 2

                   <u>x³ + 5x² + 6x</u>

                       -2x² - 10x - 12

                       <u>-2x² - 10x - 12</u>

                                    0

Therefore, quotient of the given expression will be (x - 2).
