There are very many ways to this!
We can have horizontal, vertical, some can be laying down wile others are standing up, some could be standing up and the others layed down on top of them etc.
but in this case it would be 120 ways.
Try all ways to finish the answer example:
(9-8)*2-1=1
9-(8*2)-1=-8
9-8*(2-1)=1
all answers dont equal up to 3
and because there is no possible solution this is a troll question
Answer:
(B) a square matrix
Step-by-step explanation:
The given Equations are:
,
and
Which can be written as:
![\left[\begin{array}{ccc}3&-2&2\\7&3&-26\\-1&-11&46\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D3%26-2%262%5C%5C7%263%26-26%5C%5C-1%26-11%2646%5Cend%7Barray%7D%5Cright%5D)
Thus, it is a matrix with 3 number of rows and 3 number of columns, therefore the matrix which has same number of rows and columns is a square matrix, thus, a square matrix can be form using the given system of linear equations.
