Geometric

Common ratio=3

Step-by-step explanation:

3,9,27,81 is geometric because there is a common ratio.

We know there is a common ratio because a term divided by it's previous term is the same each time.

That is

81/27=3

27/9=3

9/3=3.

So the common ratio is 3.

answer: there are 453.592 grams in a pound.

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
