Step-by-step explanation:
1) (d) -9
= -7 - (-9)
= -7 + 9
=2
2) (c) -12
3 x -4
= -12
3) (c) -140
= (-7 x - 2) x -10
= 14 x -10
= -140
4) (b) 0
= -2 x 0 x - 5
= 0
5) (a) commutative
6) (b) 1
7) (c) -1/8
8) (d) distrubutive
9) (c) -9
-18 / 2 = -9
10) (b) 2
-6/-3 = 2
11) (c) -5
15/-3
= -5
12) (a) 0
13) (c) 12 / 0 = 12
it is zero
14) (b) both are 0
15) (b) -2/1 = -2
