Step-by-step explanation:

$18 {v}^{2} - 15v - 18 \\ = 3(6 {v}^{2} - 5v - 6) \\ = 3 \{6 {v}^{2} - 9v + 4v - 6 \} \\ = 3 \{3v(2 {v} - 3) +2( 2v - 3) \} \\ = 3(2v - 3)(3v + 2)$

Answer:

Step-by-step explanation:

$\sin \theta+\cot \theta\cos \theta=\sin \theta+\displaystyle \frac{\cos \theta}{\sin \theta}\cos \theta=\frac{\sin^2 \theta+\cos ^2 \theta}{\sin \theta}=\\\frac{1}{\sin \theta}=\csc \theta$

The speed at which a certain computer can access the internet is 2 megabytes per second. How fast is this in megabytes per hour.

Ainat [17]

$Converting\ units:\\\\ 2\frac{megabytes}{second}\\\\ 1second=\frac{1}{3600}h\\\\ 2\frac{megabytes}{second}*\frac{1}{\frac{1}{3600}}=2\frac{megabytes}{second}*\frac{3600}{1}=7200\frac{megabytes}{second}\\\\If\ 1second=\frac{1}{3600}\ you\ must\ multiply\ 2*\frac{1}{3600}\ to\ convert\ 1\ second\\ into\ hour.$
