Hello there! Can you help me with this problem? Thanks!

 

Let u = - 10 18 and A = 12 5 - 2 2 - 3 4 Is u in the plane in R³ spanned by the columns of A? Why or why not? 2 Select the correct choice below and fill in the answer box to complete your choice. (Type an integer or decimal for each matrix element.) O A. No, the reduced echelon form of the augmented matrix is which is an inconsistent system. O B. Yes, multiplying A by the vector writes u as a linear combination of the columns of A.
