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

Step-by-step explanation:

The rule of dilation is D₀,₄. It means dilation by scale factor 4 with center of dilation is origin.

$\text{Scale factor}=\frac{\text{Distance between center and any point of the image}}{\text{Distance between center and corresponding point of the Preimage}}$

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

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

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

3=OB'

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

x =3

Cool Kunai ♥

Step-by-step explanation:

$3x + 5 = 14\\\\\mathrm{Subtract\:}5\mathrm{\:from\:both\:sides}\\3x+5-5=14-5\\\\Simplify\\3x=9\\\\\mathrm{Divide\:both\:sides\:by\:}3\\\frac{3x}{3}=\frac{9}{3}\\\\Simplify\\x=3$
