Answer:

A. $-\frac{9}{4}\le \:m\le \frac{9}{4}$

B. $-\frac{58}{5}$

C. $k$ or $k>7$

Step-by-step explanation:

$\left|\frac{m+3m}{3}\right|-1\le \:2$

$\left|\frac{m+3m}{3}\right|\le \:3$

$-3\le \frac{m+3m}{3}\le \:3$

$m\ge \:-\frac{9}{4}$

$m\le \frac{9}{4}$

$-\frac{9}{4}\le \:m\le \frac{9}{4}$

Answer:

–7 is not the arithmetic square root of 49 only in case we are taking it for natural number.

Step-by-step explanation:

The square root of x is that number which on squaring gives the result as x.
For example, the square root of 4 is +2 or -2. Because on squaring +2 or -2 we get the number 4.
Similarly for the case of 49, the square root might be both +7 or -7.
But if we are taking it as a natural number then -7 is not valid. Like for length, quantity or other sort of things -7 is not the arithmetic square root of 49.
