3h = 27
divide both sides by three
h= 9

You might need to use the distance formula

for the distance betwen (x1,y1) and (x2,y2) is
D= \sqrt{(x1-x2)^2+(y1-y2)^2}

so find disance between (-3,1) and (-1,3)
and (-1,3) and (3,1)
so
if we did input them
we would get 6+2 \sqrt{2}+2 \sqrt{5} which is the peirmiter

Write a matrix equation for the given systems of equations.
REY [17]

Answer:

<em></em>\left[\begin{array}{ccc}2&-6&2\\0&3&-2\\0&2&2\end{array}\right] \left[\begin{array}{ccc}x\\y\\z\end{array}\right]= \left[\begin{array}{ccc}1\\-5\\-3\end{array}\right]<em></em>

Step-by-step explanation:

Given system of equations are

2x-6y-2z = 1

3y - 2z = -5

2y + 2z = -3

given

2 x - 6 y - 2 z = 1

0 x + 3 y - 2z = -5

0 x +2y + 2 z = - 3

<em>The Matrix form of the given system of equations </em>

<em>A X = B</em>

<em></em>\left[\begin{array}{ccc}2&-6&2\\0&3&-2\\0&2&2\end{array}\right] \left[\begin{array}{ccc}x\\y\\z\end{array}\right]= \left[\begin{array}{ccc}1\\-5\\-3\end{array}\right]<em></em>
