Answer 1

Will fan and medal

Answer 2

Hey there! Do you know the definition of each of the answer choices?

Answer 3

No not really... it's confusing me a lot ;/

Answer 4

Explain?

Answer 5

This is the commutative property:

a + b = b + a

Answer 6

Does the property they give you look like that?

Answer 7

You are distributing the equation. The answer is still the same, but you change the order/arrangement. This is a prime example of the distributive property.

Answer 8

No it doesn't. This is a test I'm taking. I thought it was commutative property. But I'm still confused of why

You're new here, so I won't hold it against you for accidentally breaking it :)

Answer 12

Wait, this is a commutative property. It is saying that a + b = b + a, something related. Is that all I had to do? I didn't have to solve the equation or anything?

Answer 13

You don't need to solve the expression at all.

Yes, commutative property is a + b = b + a

3(–7 +12) = 3 • (–7) + 3 • (12) is NOT commutative property, however.

Also, keep in mind that associative property is a + (b+ c) = (a + b) + c

And, finally, distributive property is a(b + c) = ab + ac

So, is 3(–7 +12) = 3 • (–7) + 3 • (12) commutative, associative, or distributive property?

Answer 14

Wow! And, okay. Thank you! I think it's distributive?

Answer 15

Lol, this is much easier, now. I'm going to say Distributive.

Answer 16

Correct!

Answer 17

Yay!
