B) 6
C) 12
D) 18
E) 15​

Answer 1

Respuesta:

3

Explicación paso a paso:

Si a @b= 3(b @a) - 2a.

Calcula (6 @ 2)

(6 @ 2) = 3(2 @ 6 ) - 2(6)

(6 @ 2) = 3( 3(6@2) -2(2) ) - 2(6)

(6 @ 2) = 3( 3(6@2) -4 ) - 12

(6 @ 2) = 9(6@2) -12 - 12

(6 @ 2) -9(6@2) = -24

-8(6@2) = -24

(6 @ 2) = -24/-8

(6 @ 2) = 3
