What is X if

umka2103 [35]

Answer:

$X = \begin{bmatrix} - 4 & 1 \\ - 2 & - 7\end{bmatrix}$

Step-by-step explanation:

$\begin{bmatrix} - 1 & - 2\\ 4 & 8\end{bmatrix} +X = \begin{bmatrix} - 5 & - 1\\ 2 & 1\end{bmatrix}$

$X = \begin{bmatrix} - 5 & - 1\\ 2 & 1\end{bmatrix}-\begin{bmatrix} - 1 & - 2\\ 4 & 8\end{bmatrix}$

$X = \begin{bmatrix} - 5-(-1) & - 1-(-2)\\ 2-4 & 1-8\end{bmatrix}$

$X = \begin{bmatrix} - 5+1 & - 1+2\\ 2-4 & 1-8\end{bmatrix}$

$X = \begin{bmatrix} - 4 & 1 \\ - 2 & - 7\end{bmatrix}$

elise is changing the dimensions of her garden. the length is 20 feet longer than its width. if she decreases this length by 8 f

vitfil [10]

Let x be the initial width, then the initial length is x+20.
If Elise decreases this length by 8 feet, she will get the new length x+20-8=x+12.

If Elise increases the width by 10 feet, she will get the new width x+10.

The new perimeter will be x+12+x+12+x+10+x+10=4x+44=172, 4x=172-44, 4x=128, x=128÷4, x=32.

The initial width is 32 ft and the initial length is 32+20=52 ft.

The new width will be 32+10=42 ft, the new length will be 32+12=44 ft.
