hey mate please help to solve both questions

complete= thumbs UPUPUPUP!!!! :) ok

and take ip to 30-40 minutes but pleaee solve

The vector x is in a subspace H with a basis B - {b, b2]. Find the B-coordinate vector of x. b2 E- Question 14 Which of the following statements is(are) false? D)The cofactor expansion of det A down a column is equal to the cofactor expansion along a row C) The determinant of a triangular matrix is the sum of the entries on the main diagonal A and C B)An n x n determinant is defined by determinants of (n - 1) (n - 1) sub matrices B and D A, C and D A)The (i.)) -cofactor of a matrix A is the matrix Aij obtained by deleting from A its i throw and j th column B, C. and D Question 15 "A- [4 2 and 3 - 6 [1] Determine the condition for which det(A + B) = det A + det B. 1+ d-a a=1-d+c 1+d+a2c=0 1+d+a+2c=0 The equation det(A + B) = det A + det B is true always and there is no need for any condition a=c-1-2
