$\bf \textit{Law of Cosines}\\ \quad \\
c^2 = {{ a}}^2+{{ b}}^2-(2{{ a}}{{ b}})cos(C)\qquad 
\begin{cases}
a=2\\
b=3\\
c=4

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

uranmaximum [27]

Answer:

$3.2t-2.4$

Step-by-step explanation:

The polynomial given for simplification is:

$-3.6-1.9t+1.2+5.1t$

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

The commutative property of addition states that:

$a+b=b+a$

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,

$-1.9t+5.1t+1.2-3.6$

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

$(-1.9+5.1)t+(1.2-3.6)$

Simplifying the above expression, we get:

$(-1.9+5.1)t+(1.2-3.6)\\3.2t-2.4$

Therefore, the simplified form is $3.2t-2.4$
