Q.

69×(-7,2)+31×(-7,2)​

Penjelasan dengan langkah-langkah:

69 × (-7,2) + 31 × (-7,2)

= 69 × (-7,2) + 31 × (-7,2)

= (-496,8) + 31 × (-7,2)

= (-496,8) + (-223,2)

= -720

69 × ( - 7,2 ) + 31 × ( - 7,2 )

= (69 × (-7,2)) + (31 × (-7,2))

= - (69 × 7,2) - (31 × 7,2)

= - 496,8 + ( - 223,2 )

= - 496,8 - 223,2

= - (496,8 + 223,2)

=> - 720
