the value of x = 9 (option B)

Step-by-step explanation:

To determine x, we would use a scale factor.

Scale factor = ratio of corresponding sides of both figures

Scale factor = the side in the image/the side in the old image


(12)/(2)=(54)/(x)

cross multiply:

12x = 54 *2

12x = 108

DIvide both sides by 12:

12x/12 = 108/12

x = 9

12/2 = 54/9 = 6

scale factor = 6

Hence, the value of x = 9 (option B)
