How do you use the associative property to write an expression equivalent to (w+9) + 3

The equivalent expression for the given expression (w+9) + 3 using associative property is w + 12

Solution:

Given that, expression is (w + 9) + 3

We have to find how do we can use the associative property to write an expression equivalent to (w + 9) + 3

The associative property states that you can add or multiply regardless of how the numbers are grouped

By above definition, we get

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

So, now let us apply the above property to the given expression,

Then, (w + 9) + 3 = w + (9 + 3) = w + 12

Hence, the equivalent expression for the given expression is w + 12
