20 por 2, eso te da 40 lo que es la segunda pieza, finalmente multiplica 20 por 6 lo cual te da 120, sumas esas 3 cifras: 20+40+120 y tendras como resultado 180, denada uwu

Answer 2

20 feet

Explanation:

1st piece = x

2nd piece = 2x

3rd piece = 6x

x+2x+6x=180

9x=180

x=20

so the first piece is 20 feet, the second is 40, and the third is 120.
