Question

I need help with this question....

Name the algebraic property demonstrated in the example below:
(2 + x) + y = 2 + (x + y) (1 point)

Commutative Property of Addition
Associative Property of Addition
Distributive Property
Transitive Property

Answer 1

One would usually associate this with commutative property, HOWEVER, since this has parenthesis (which does make a huge difference in some cases) it would be associative property.

Answer 2

thank you

Answer 3

You're welcome :)

Answer 4

could you help with another question?

Answer 5

Can try...

Answer 6

Name the algebraic property demonstrated in the example below:
x • y • z = y • x • z (1 point)

Distributive Property
Transitive Property
Associative Property of Multiplication
Commutative Property of Multiplication

Answer 7

This one would be commutative because the terms are just switched around but it mean the same thing.

Answer 8

but how

Answer 9

Just another thing to throw off there: if this had a parenthesis then it would be the associative property of multiplication.

Answer 10

ohhhh ok
thx :)

Answer 11

"The word "commutative" comes from "commute" or "move around", so the Commutative Property is the one that refers to moving stuff around. For addition, the rule is "a + b = b + a"; in numbers, this means 2 + 3 = 3 + 2. For multiplication, the rule is "ab = ba"; in numbers, this means 2×3 = 3×2." -- purplemath.com

No problem :)
