Answer: 
Step-by-step explanation:
<u>The goal of the question</u>
Find the value of 2abcosC
<u>Given information</u>
a = 4
b = 3
c = 2
<u>Given formula (Law of Cosine)</u>

<u>Substitute values into the formula (Leave 2abcosC as it is)</u>

<u>Simplify the exponents</u>

<u>Simplify by addition</u>

<u>Add 2abcosC on both sides</u>


<u>Subtract 4 on both sides</u>


Hope this helps!! :)
