En resumen

A = 4k B = 5k C = 6k A(B)(C) = 960 4k(5k)(6k) = 960 120(k ^ 3) = 960 k ^ 3 = 8 k = 2 Entonces A + B - C A = 4(2) = 8 B = 5(2) = 10 C = 6(2) = 12 8 + 10 - 12 18 - 12 6.

Mejor respuesta

A = 4k

B = 5k

C = 6k

A(B)(C) = 960

4k(5k)(6k) = 960

120(k ^ 3) = 960

k ^ 3 = 8

k = 2

Entonces A + B - C

A = 4(2) = 8

B = 5(2) = 10

C = 6(2) = 12

8 + 10 - 12

18 - 12
