[(M^2N^2-MN)(M^2N^2+MN)]/MN

GaryK [48]

Answer:

Step-by-step explanation:

M²N² - MN = MN (MN - 1)

M²N² + MN = MN (MN + 1)

$\frac{(M^{2}N^{2}-MN)(M^{2}N^{2}-MN)}{MN}= \frac{MN(MN-1) * MN(MN + 1)}{MN}\\$

= (MN - 1) * MN * (MN + 1)

= (MN - 1)(MN +1) MN {(a+ b)(a - b) = a² - b² }

= (M²N² - 1²) * MN

= (M²N² - 1)MN

Given -1/2x>6 choose the solution set

kondaur [170]

-1/2x > 6

All you have to do is divide 6 by -1/2, which is -3. The answer is x < -3, the sign got flipped because you divide by a negative number.

Can you guys help me with this?

Blababa [14]

Answer:

We have been given many sequences below:

The sequence is said to be geometric if there is same ratio between consecutive terms

$\frac{a_n}{a_{n-1}}$

So we will check all the sequences one by one:

(1) $\frac{-9}{-2.7}=\frac{10}{3}$

$\frac{-30}{-9}=\frac{10}{3}$

$\frac{-100}{-30}=\frac{10}{3}$ .

Hence, geometric

(2) $\frac{2.5}{-1}=-2.5$

$\frac{-6.25}{2.5}=-2.5$

$\frac{15.625}{-6.25}=-2.5$

Hence, geometric.

(3) $\frac{9.2}{9.1}=0.010$

$\frac{9.3}{9.2}=0.010$

$\frac{9.4}{9.3}=0.010$

Hence, geometric.

(4) $\frac{0.8}{8}=0.1$

$\frac{0.08}{0.8}=0.1$

$\frac{0.008}{0.08}=0.1$

Hence, geometric.

(5) $\frac{-4}{4}=-1$

$\frac{-12}{-4}=3$

Ratio is not same hence, not geometric.
