aplique a propriedade distributiva e efetue
6.(3+4)
3.(a+c)
8.(3+2)
12.(a+b)
7.(4+3)
9.(2+7)

Answer 1

6.(3 + 4) =
18 + 24 = 42

3.(a + c) =
3a + 3c

8.(3 + 2) =
24 + 16 = 40

12.(a + b) =
12a + 12b

7.( 4 + 3) =
28 + 21 = 49

9.(2 + 7) =
18 + 63 = 144

Answer 2

6.(3+4) = 6.3 + 6.4
3.(a+c) = 3a + 3c
8.(3+2) = 8.3 + 8.2
12.(a+b) = 12a + 12b
7.(4+3) = 7.4 +7.3
9.(2+7) = 9.2 +9.7
