B is correct. Also, if you have a number such as 876543 and add the digits, it is 33. If you did not know this was divisible by three, you could add 3+3 and get 6, which is divisible by three, making 876543 divisible by three.

Answer:

The answer is option 3.

Step-by-step explanation:

The steps are :

$3 \sqrt{2} (5 \sqrt{6} - 7 \sqrt{3})$

$= (3 \sqrt{2} )(5 \sqrt{6} ) - (3 \sqrt{2} )(7 \sqrt{3} )$

$= 15 \sqrt{12} - 21 \sqrt{6}$

$= 15 \sqrt{4 \times 3} - 21 \sqrt{6}$

$= 15(2) \sqrt{3} - 21 \sqrt{6}$

$= 30 \sqrt{3} - 21 \sqrt{6}$

Answer:

m^2-2m-3

Step-by-step explanation:

$\frac{6m \times (m - + 1)}{(m - 3)(m + 1)} + \frac{m \times (m - 3)}{(m - 3)(m + 1)} \\ \frac{ {6m}^{2} + 6m}{ {m}^{2}- 2m - 3} + \frac{ {m}^{2} - 3m }{ {m}^{2} - 2m - 3 } \\ \frac{ {7m}^{2} + 3m}{ {m}^{2} - 2m - 3}$
