State the property that justifies the following: 9(x + 3) = 9x + 27
Additive Inverse Distributive Property Associate Property of Addition Commutative Property of Addition
when you multiply an outer number (in your case 9) by the values in the parentheses, do you know what you are doing?
distributing
The distributive property because you are distributing the 9 to the x and the 3
perfect, so which property do you think it is?
so its distributive
if youre distributing, then it kind of already gives you your answer
ok thanks
sure thing :)
what about this one
3)(6)(9) = (6)(9)(3) Multiplicative Identity Additive Inverse Distributive Property Associate Property of Addition Commutative Property of Addition Commutative Property of Multiplication Associate Property of Multiplication
communitive property of multiplication
cool thought so
Associative Property: When three or more numbers are multiplied, the product is the same regardless of the grouping of the factors. For example (2 * 3) * 4 = 2 * (3 * 4)
i disagree with that @sammyx335
ohh its associative
yea, thats what i would put
ok
what about this
careful, you're changing the positions of factors
(3)(6)(9) = (6)(9)(3) ab = bc is what property ? :)
im having trouble understanding what you mean @ganeshie8
me to
@ganeshie8
in this example, there are three different variables that are being moved in their position of multiplication. in that, would it not be associative?
associative is about grouping
Where is Lord Ganesh?
a(bc) = (ab)c is associative property
Notice that we're not changing the position of numbers here
variables*
so thats what this is(9)[(8)(7)] = [(9)(8)](7)
im still confused because (a)(bc) will still get you the same thing if a=1, b=2, c=3, 1(2*3) = (1*2)(3)
3 x 6 x 9 = (3x6) x 9 = 3 x (6x9) (associative) 3 x (6x9) = (6x9) x 3 (commutative)
Yes alygirl, (9)[(8)(7)] = [(9)(8)](7) is associative property
thanks
yes @TechnoSoul , thats the reason they are called properties of `equalities` :)
haha i understand that part, I'm just still a bit confused. oh well, its alright. I dont want to confuse @alyygirl anymore than i have already XD
