ini juga tolong dijawab oke
Jawaban:
1. a=1 b=5 c=4
b+c= 5+4= 9
a×(b+c) = 1×(5+4) = 1×9= 9
a×b= 1×5= 5
a×c = 1×4= 4
(a×b) + (a×c) = (1×5) + (1×4) = 9 (kurang lebih gitu, kalo salah maap)
2. a= -2 b= 6 c= -3
6+ -3= 3
-2×(6+ -3) = -2×3= 1
-2×6= -12
-2×-3= 6
(-2×6) + (-2×-3) = -12+6= 6
3. a=3 b= -7 c=2
-7+2= 5
3×(-7+2) = 15
3× -7= -21
3×2= 6
(3× -7) + (3×2) = -21+6= 15
4. a= -4 b= -8 c= -1
-8+ -1= -9
-4×(-8+ -1) = 36
-4× -8= 32
-4× -1= 4
(-4× -8) + (-4× -1) = 32+4= 36
lebih dan kurang minta maaf
sekian terima kasih!
