Let's take a look at the given expression.
8+(9t+4)
We are asked to simplify this expression. Remember that we need to group like terms before performing a sum. We can use the Properties of Real Numbers in order to do so. Let's do it!
Property/Operation
Before
After
Commutative Property of Addition
8 + ( 9t+ 4)
8 + ( 4+ 9t)
Associative Property of Addition
8 + (4+9t )
( 8 + 4 ) + 9t
Add Terms
( 8 + 4 ) + 9t
12 + 9t
Since 12 and 9t are not like terms, we cannot simplify further.
