Suppose u is a 3 x 3 upper triangular matrix, with entries ay, and l is a 3 x 3 lower triangular matrix with entries by then det u = enter the value terms of the matrix entries aj, where aij is entered as a ij and det l=l of the determinant in preview syntax error preview syntax error get : video written example

what do you need me to answer?

step-by-step explanation:

multiplication is multiplication.   it might feel harder depending on what level of math you are in, but generally it will be the same old stuff, while implementing some new concepts and methods of solving work.

y∈r, 8> y≥0

hope i !

p.s the first bit only matters if you know what that means.

p.p.s brainliest would really
