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!
