Respuesta :

The length of AB is 18

Answer:

AB = 18

Step-by-step explanation: AB = BC

                      4x -2 = 3x + 3... subtract 3x and add 2

                      1x = 5.. divide both sides by 1 and x= 5

                                       plug x into 4x -2

                                           4(5) -2 = 18
