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:
96x^2 - 108 - 663
Step-by-step explanation:
(8x + 17)(12x - 39)
96x^2 - 312x + 204x -663
96x^2 - 108 - 663
Answer:
In year 2039 both the events will happen again.
Step-by-step explanation:
We are given the following in the question:
Family reunion:
Every 7 year
Update the family tree:
Every 6 years
1997 was the year when they had a family reunion as well as they updated their family tree.
We have to find the year in which both the events will occur together.
We find the lowest common multiple of 7 and 6.

Thus, after 42 years both the event will happen again.
Year:

Thus, in year 2039 both the events will happen again.
