Answer:
Choices C and D
Step-by-step explanation:
The most simplest way is just to solve each one and see which two have the same answer as the first expression.
But you could also see that both of the 
are going to cancel each other out so you are left with 
which is also choice C.
For choice D I distributed the negative one to the insides of the parenthesis that left me with 
which is the same expression as the first one.

<h2>
Answer:</h2>
is 3 ohms
<h2>
Step-by-step explanation:</h2>
In a circuit containing two resistors 
and connected together in parallel, the total resistance 
is given by;
---------(i)
<em>Make </em><em> subject of the formula;</em>
=> 
=> 
=> 
---------------(ii)
From the question,
= 6Ω
= 2Ω
Substitute these values into equation (ii) as follows;
=> 
= 3Ω
Therefore, the value of = 3 ohms or = 3Ω
