Combine like terms to create an equivalent expression -3.6-1.9t+1.2+5.1t

Step-by-step explanation:

The polynomial given for simplification is:

Now, we combine like terms using the commutative property of addition.

The commutative property of addition states that:

So, the order can be shuffled when we add terms.

The terms containing 't' are grouped together and the constant terms are grouped together. This gives,

Now, we group them using associative property and converse of distributive property as:

Simplifying the above expression, we get:

Therefore, the simplified form is
