It's talking about the decimal places. The third one is already given to you, 0.14. It's 7 times 2, which is 14 but the decimal is moved two places to the left. So by that information, for the tenth, the decimal would be moved once to the left. For the ones, the decimal isn't moved.

Ones: 7 * 3 = 21

Tenths: 7 * 1 = 7

Hundredths: 7 * 2 = 14

So the answer is 21 + 0.7 + 0.14

Answer:

clockwise from left, the missing side lengths are 8 m, 13 m, 8 m

Step-by-step explanation:

The perimeter of the figure is the sum of the lengths of its sides. Sides with the same hash mark have the same length, so the perimeter (in meters) is ...

38 = (3x+1) +(2x) +(9) +(2x)

38 = 7x +10

28 = 7x . . . . . . subtract 10

4 = x . . . . . . . . divide by 7

Then the short sides are ...

2x = 2·4 = 8 . . . meters

and the long side is ...

3x+1 = 3·4 +1 = 13 . . . meters
