Help please. I need to find the value of x

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

 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

1) c 2143.6 cm

2) c 113.0 m

3) a 33.5 ft

4)   d 2 cm

5) c 20 mm

6) 180 in

7) d 120 ft

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
