Simplify by using the associative property of multiplication.
(12+a)+ 17
Using the associative property of multiplication, the expression can be simplified to:
12 + a + 17 = 29 + a
To simplify the expression (12+a)+17 using the associative property of multiplication, we need to rearrange the terms in a way that groups the numbers together.
First, we can change the order of addition by moving the term 17 to the front:
17 + (12+a)
Now, using the associative property of multiplication, we can group the numbers together. However, note that the associative property of multiplication doesn't apply directly to addition. So, we can simplify the expression further by combining like terms:
17 + 12 + a
Therefore, the simplified expression is 29 + a.
