Finding an Equivalent Expression
The associative property of addition states that you can move the terms that are inside the parentheses and still have the expression remain true. So, in the answer above, I moved 5 out of the parentheses and x into the parentheses. No matter the value of x the value of the expression will remain the same
Examples and Proof
Another example of the associative property could be (1+6)+3 = 1+(6+3). To prove this statement we can evaluate each side of the expression.
First, let's do (1+6)+3
Next, let's do 1+(6+3)
As you can see both of these expressions are the same, thus proving that the associative property works in this situation.
Answer:
0
Step-by-step explanation:
any thing that is multiplied by 0 will be 0
2 of the them have to seat in the front row and the two others in the back
Answer:
Yes , the products of both expressions are the same
Step-by-step explanation:
Given
(-5 + x)( x + 4)
Using the distributive property we have
-5xx -5x4 + xxx +xx4
Negative times positive becomes negative
-5x - 20 + x^2 + 4x
Also (5 + x)(x - 4)
Using the distributive property
5xx +5-4 + xxx +xx-4
5x^2 -20 + x^2 - 4x
The product of -5 + x and x + 4 is equal to the product of 5 + x and x - 4
