3x(1)=3x

OpenStudy (anonymous):

So, what would the question be?

OpenStudy (anonymous):

what is the property?

OpenStudy (anonymous):

property of x?

OpenStudy (anonymous):

the whole problem like Identity Property for Multiplication Inverse Property for Addition Commutative for Addition Distributive Property

OpenStudy (anonymous):

identity problem for multiplication is that a number does not change when that number is multiplied by 1. so, \[3x \times 1 = 3x\]

OpenStudy (anonymous):

am i going in the right direction here?

OpenStudy (anonymous):

yeah that's right thanks you got it right

OpenStudy (anonymous):

so i carry on for the other 3?

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

Inverse property of addition states that a number added to its opposite integer will equal to zero. \[3x + (-3x) = 0\]

OpenStudy (anonymous):

there's no addition its multiplication so it couldn't be inverse plus its answer is zero

OpenStudy (anonymous):

inverse property of multiplication states that when a number multiplies its inverse, the answer equals to 1. \[3x \times \frac{ 1 }{ 3x } = 1\]

OpenStudy (anonymous):

...hm

OpenStudy (anonymous):

Commutative property of addition states that changing the order of numbers in addition does not matter, \[3x + 0 = 2x + x = x + 2x = 0 + 3x\]

OpenStudy (anonymous):

The distributive property allows you to multiply a sum of numbers by multiplying each number and then adding the products. \[x (1+2) =( x \times 1) + (x \times 2) = x + 2x = 3x\] or \[3x(1 + [-1]) = (3x \times 1) + (3x \times -1) = 3x - 3x = 0\]

OpenStudy (anonymous):

it looks like distributive
