QUIZ(10/100)

...

Jika:

ab = 24
ac = 14


a( b + c) + 2 = ....​

Penjelasan dengan langkah-langkah:

ab = 24

ac = 14

a(b + c) + 2

Sifat aljabar → a(b + c) = ab + ac

= ab + ac + 2

= 24 + 14 + 2

= 38 + 2

= 40

#Koreksi

Diketahui :

ab = 24

ac = 14

Ditanya :

a( b + c) + 2 = ....*

Jawab :

  • a( b + c) + 2
  • ( a × b ) + ( a × c ) + 2
  • ab + ac + 2
  • 24 + 14 + 2
  • 38 + 2
  • 40

Jadi, hasil dari a( b + c) + 2 adalah 40.
