Answer:

VW = 8

Step-by-step explanation:

Because this trapezoids are similar

PS : TW = PQ : TU = QR : UV = RS : VW

We can take for example this equation

QR : UV = RS : VW

6 : 4 = 12 : VW

6*VW = 4*12

VW = 4*12/6 = 8

Answer:  x = 8

Step-by-step explanation:

From all the other dimensions given, you can see that the small trapezoid's sides are each 2/3 of the large trapezoid.

6= 2/3(9) . 4= 2/3(6) .12= 2/3(18) .  so take 2/3(12) = 8
