The second option

Step-by-step explanation:

The given system of equation is

x+2y=3

-x+y+z=2

y-2z=-3

The augment matrix is obtained by combining the coefficient matrix with the constant matrix to obtain;

$\left[\begin{array}{cccc}1&2&0&|3\\-1&1&1&|2\\0&1&-2&|-3\end{array}\right]$

Note that the absence of z, in the first equation means its coefficient is zero. The same thing applies to x in the last equation.

The correct choice is the second option.

Triangle that makes it Look like a Reversed P is 312.5 ft, the long rectangle minus the bottom triangle makes an area of 280 ft , the last triangle is 32 ft

so that makes all of them have an area of 624.5
