Question

Lois wrote the equation shown below.

4x + 12y = 4(x + 3y)

Which property did Lois apply?

Answer 1

commutative property of addition

associative property of addition

distributive property of addition

addition property of equality

Answer 2

That dude is smart. He was correct. We usually have questions like "At what step was Lois wrong?" :P

Answer 3

Well. Do you have any guesses for this one?

Answer 4

ummm... b?

Answer 5

Something to help out you in general with these type questions:
apply process of elimination first!

:-)

Answer 6

\( \color{Black}{\Rightarrow a + (b + c) = (a + b) + c}\)
Associative ^

\( \color{Black}{\Rightarrow a( b + c) = ab + ac }\)
Distributive ^

\( \color{Black}{\Rightarrow a + b = b + a }\)
Commutative ^

Answer 7

Which one in the examples according to you is closest?

Answer 8

the 2nd

Answer 9

I don't think so.

Answer 10

??

Answer 11

2nd one doesn't look like the property that Lois was talking about.

Answer 12

oooooo commutative

Answer 13

Nah

Answer 14

what ? thn im lost

Answer 15

How did you get commutative and associative right there? Can you explain?

Answer 16

Hint: look at the thing as \(4(x + 3y) = 4x + 12y\) instead.

Answer 17

so it is assos

Answer 18

How so? If you think that it is associative, then can you tell me what a, b and c are in this example?

Answer 19

because it looks the same as the example

Answer 20

Well. Can you tell me what \(a,b,c\) are in the example?

Answer 21

The associative property says \(a + (b + c) = (a + b) + c\).

Answer 22

thats wat im gonna go with

Answer 23

What are a,b and c?

Answer 24

commutative property of addition

associative property of addition

distributive property of addition

Answer 25

Not the choices..

Answer 26

wat do u think it is

Answer 27

It's one of the choices.

Answer 28

Its distributive... which is what she prolly meant when she said the second one^^
