The rule that describes this translation is
In order to list the measurements from smallest to largest, we convert all the measurement to a common unit. In this item, we convert the given to meters, m.
A. The conversion factor to be used here is 1 m = 100 cm
(7 cm)(1 m / 100 cm) = 0.07 m
B. Conversion factor: 1 m = 1000 mm
(18 mm) (1 m / 1000 mm) = 0.018 m
C. Let us list this as is, 1 m
D. The conversion factor here is 1 m = 10 dm
(3 dm)(1 m / 10 dm) = 0.3 m
By the converted values, we are then able to arrange the given measurements.Hence, the arrangement should be 18 mm, 7 cm, 3 dm, and 1 m.

3(2d - 7) = (2 + 4d)2
distribute
3*2d -3*7 = 2*2 +2*4d
multiply
6d -21 = 4 +8d
subtract 6d from each side
6d-6d-21 = 4 +8d-6d
-21 = 4+2d
subtract 4 from each side
-21 -4 =4+2d-4
-25 =2d
divide by 2
-25/2 =d
