Answer:

(d) -15

Step-by-step explanation:

Given system of equations are:

\begin{cases}kx-5y=2\\\\6x+2y=7\end{cases}

Since, given system of equations have no solution.

\therefore \frac{k}{6}=\frac{-5}{2} \neq\frac{2}{7}

\implies \frac{k}{6}=\frac{-5}{2}

\implies k=\frac{6(-5)}{2}

\implies k=\frac{-30}{2}

\implies k=-15

Could you help me with this. <br><br> Express in simplest radical form.<br> 162<br><br> ​
Ivanshal [37]

Answer:

The square root of 162 in its simplest form means to get the number 162 inside the radical √ as low as possible.

Here is how to do that! First we write the square root of 162 like this:

√162

The largest perfect square of the factors of 162 is 81. We can therefore convert √162 like this:

√81 × 2

Next, we separate the numbers inside the √ as such:

√81 × √2

√81 is a perfect square that equals 9. We can therefore put 9 outside the radical and get the final answer to square root of 162 in simplest radical form as follows:

9√2
