The perimeter o f a rectangle is 70 in., and the width is 9 in.
what is the length?

26 inches

Step-by-step explanation:

First, subtract 18 by 70, since there will be 2 width amounts in the perimeter:

70 - 18

= 52

Then, divide this by 2, to find the length:

52/2

= 26

So, the length is 26 inches.

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
