Answer:

s=-1

Step-by-step explanation:

2s-2=-9-5s

<u>Add 2 to both sides:</u>

<u />2s-2+2=-9-5s+2

2s=-5s-7

<u>Add 5x from both sides:</u>

<u />2s+5s=-5s-7+5s

7s=-7

<u>Divide both sides by 7:</u>

<u />\frac{7s}{7}=\frac{-7}{7}

s=-1

Answer:

We conclude that:

3\cdot \:2\begin{pmatrix}-2&3&0\\ -4&2&6\\ 6&-5&6\end{pmatrix}=\begin{pmatrix}-12&18&0\\ -24&12&36\\ 36&-30&36\end{pmatrix}

Hence, option B is correct.

Step-by-step explanation:

Given the expression

3\times 2\begin{pmatrix}-2&3&0\\ \:-4&2&6\\ \:6&-5&6\end{pmatrix}

solving

3\times 2\begin{pmatrix}-2&3&0\\ \:-4&2&6\\ \:6&-5&6\end{pmatrix}

Scalar Multiplication: Multiply each of the matrix elements by a scalar

=\begin{pmatrix}3\cdot \:2\left(-2\right)&3\cdot \:2\cdot \:3&3\cdot \:2\cdot \:0\\ 3\cdot \:2\left(-4\right)&3\cdot \:2\cdot \:2&3\cdot \:2\cdot \:6\\ 3\cdot \:2\cdot \:6&3\cdot \:2\left(-5\right)&3\cdot \:2\cdot \:6\end{pmatrix}

Simplify each element

=\begin{pmatrix}-12&18&0\\ -24&12&36\\ 36&-30&36\end{pmatrix}

Therefore, we conclude that:

3\cdot \:2\begin{pmatrix}-2&3&0\\ -4&2&6\\ 6&-5&6\end{pmatrix}=\begin{pmatrix}-12&18&0\\ -24&12&36\\ 36&-30&36\end{pmatrix}

Hence, option B is correct.

The length of a rectangle is 3 centimeters longer than the width. The perimeter of the rectangle is less than 15cm.
kozerog [31]

Answer:

15>4W+6

Step-by-step explanation:

Perimeter is:
P = 2(L+W)

15>2L+2W

L=W+3 = One length

2W+6= Both lengths

2W+2W+6=4W+6

4W+6 is perimeter

15>4W+6
