Indicate which property is illustrated in step 2.
step 1 9 + (5 + 7) + 0 = 9 + (7 + 5) + 0
step 2 = (9 + 7) + (5 + 0)
step 3 = (9 + 7) + 5
step 4 = 16 + 5

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x

the answer is 62.8 cubic units

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x

4932,9180,7625 are divisible by 9
