Which of the following correctly demonstrates the use of the Commutative Property of Multiplication?(1 point)
Responses
11(b+z)=11b+11z
11 left parenthesis b plus z right parenthesis equals 11 b plus 11 z
3(b10+4)=3(4+b10)3
3 left parenthesis b superscript 10 baseline plus 4 right parenthesis equals 3 left parenthesis 4 plus b superscript 10 baseline right parenthesis 3
2(b10+z11)=(b10+z11)⋅2
2 left parenthesis b superscript 10 baseline plus z superscript 11 baseline right parenthesis equals left parenthesis b superscript 10 baseline plus z superscript 11 baseline right parenthesis times 2
z11⋅2=z11+2
z superscript 11 baseline times 2 equals z superscript 11 baseline plus 2

Which step contains an error using the Commutative Property of Addition in verifying 8+x2+17x−x2+4=10+4x2+10x−4x2+2+7x?
Step 1: 8+4+x2−x2+17x=10+2+10x−4x2+7x +4x2
Step 2: 8+4+17x+x2−x2=10+2+4x2−4x2+10x+7x
Step 3: 12+17x+x2=12−x2+17x

No mistake was made.
The mistake was made in Step 2.
Step 2: 8+4+17x+x^2−x^2=10+2+4x^2−4x^2+10x+7x
The mistake is in the terms "4x^2−4x^2" which should be "−4x^2+4x^2".
So the corrected step should be:
Step 2: 8+4+17x+x^2−x^2=10+2−4x^2+4x^2+10x+7x
Step 2: 8+4+17x+x^2−x^2=10+2+4x^2−4x^2+10x+7x
The mistake is in the terms "4x^2−4x^2" which should be "−4x^2+4x^2".
So the corrected step should be:
Step 2: 8+4+17x+x^2−x^2=10+2−4x^2+4x^2+10x+7x
how right was this?
