5n+1+5n+2+5n+4
5n-1+5n-2+5n-3
​

Answer 1

Respuesta:

15n+7,15n−6

Explicación:

((5n+5n+5n)+(1+2+4)),5n−1+5n−2+5n−3

 (5n+5n+5n)+(1+2+4)(5n+5n+5n)+(1+2+4)  a  15n+715n+7.

15n+7,5n-1+5n-2+5n-3

15n+7,5n−1+5n−2+5n−3

15n+7,((5n+5n+5n)+(-1-2-3))

15n+7,((5n+5n+5n)+(−1−2−3))

  (5n+5n+5n)+(-1-2-3)(5n+5n+5n)+(−1−2−3)  a  15n-615n−6.
