Indicate which property is illustrated in step 4.

step 1
(-8) + 8 + 2(8 + 2)
=
(-8) + 8 + (2 • 8) + (2 • 2)

step 2

=
(-8) + 8 + (16) + (4)
step 3

=
(-8) + 8 + 20
step 4

=
0 + 20
step 5

=
20

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
