The perimeter of a rectangle is 26 m. the length is 4 m more than two times the width. find the length and the width of the rectangle.

Make 2(length) + 2(width) add up to 26 in an equation.

2(2x + 4) + 2(x) = 26

4x + 8 + 2x = 26

6x + 8 = 26

6x = 18

x = 3

Length: 2(3) + 4 = 10 m

Width: (3) = 3 m

the mistake in the pattern is that :

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
