Answer:

The answer to your question is:  (2a - 1) / 4

Step-by-step explanation:

         \frac{12a^{2} - 3}{2} (2a + 1)^{-2}  ( \frac{6}{(2a +1)^{-1} } \\

        \frac{3(4a^{2} -1)}{2} \frac{1}{(2z + 1)^{2} } (\frac{2a + 1)}{6}

        \frac{3(2a + 1)(2a- 1) (2a + 1)}{12(2a + 1)(2a + 1)}

The difference between two numbers is 7194. If the subtrahend is 12,806, find the minuend.
valentina_108 [34]

<u>Answer:</u> The minuend is 20000

<u>Step-by-step explanation:</u>

To calculate the minuend, we use the equation:

\text{Subtrahend}=\text{Minuend-Difference}

We are given:

Difference between the two numbers = 7194

Subtraend = 12806

Putting values in above equation, we get:

\text{Minuend}=12806+7194\\\\\text{Minuend}=20000

Hence, the minuend is 20000
