Answer:
Remember, a homogeneous system always is consistent. Then we can reason with the rank of the matrix.
If the system Ax=0 has only the trivial solution that's mean that the echelon form of A hasn't free variables, therefore each column of the matrix has a pivot.
Since each column has a pivot then we can form the reduced echelon form of the A, and leave each pivot as 1 and the others components of the column will be zero. This means that the reduced echelon form of A is the identity matrix and so on A is row equivalent to identity matrix.

Answer:
5w -6
Step-by-step explanation:
(W2 – 4w - 1)+(-5 + 5w2 – 3w)
combine like terms in the 2 groups
(-2w-1)+(-5+5w(2) -3w)
(-2w-1)+(-5+10w-3w)
(-2w-1)+(-5+7w)
now add/subtract all
5w -6
