Question

Indicate which property is illustrated in Step 4.

Step 1 11 + 12x - 11 - 2x + 3 = 11 + (12x - 11) - 2x + 3
Step 2 = 11 + (-11 + 12x) - 2x + 3
Step 3 = [11 + (-11)] + (12x - 2x) + 3
Step 4 = 0 + (12x - 2x) + 3
Step 5 = (12x - 2x) + 3
Step 6 = (12 - 2)x + 3
Step 7 = 10x + 3

associative
additive identity
commutative
additive inverse

Answer 1

it added a 0

Answer 2

so would that make it um identity

Answer 3

identity is when it get canceled out which would be in step 4 to step 5
inverse is when you add or multiply the opposite to get to the identity

Answer 4

so inverse ugh i knew it ok inverse is to 0
and identity is to when 0 is canceled
associative is grouping
commutative is like a mirror

Answer 5

yes :)
