Question

3(a + b) = 3a + 3b is an example of which algebraic property?

Distributive Property

Associative Property of Addition

Commutative Property of Addition

Symmetric Property

Answer 1

what did you get?

Answer 2

im confused

Answer 3

so you're completely stuck and haven't gotten anywhere?

Answer 4

nope

Answer 5

the Symmetric Property is the idea that

if x = y, then y = x

so that answer choice is eliminated since this isn't what we want

Answer 6

what is the Commutative Property of Addition ?

Answer 7

addends can be added in any order and the sum is always the same.

Answer 8

good

Answer 9

basically the idea that

x+y = y+x

for any real numbers x and y

Answer 10

so that's out too

Answer 11

how about the Associative Property of Addition

what does that say?

Answer 12

it doesn't matter how you add them, the totals are always same.

Answer 13

close, more like how the grouping doesn't affect the answer

Answer 14

ok

Answer 15

so

a+(b+c) = (a+b)+c

for any real numbers a, b, c

Answer 16

so that choice is out

Answer 17

the only thing left is the distributive property

Answer 18

and it turns out that the distributive property is

x(y+z) = x*y + x*z

which is exactly what is used in the original problem

Answer 19

thank you

Answer 20

you're welcome
