Compute each determinant given that the following determinant has the given value. Showing some work (if possible) allows your instructor to assign partial credit. Your final answer should be a single integer number. [5 points each] f h -10 ~2d ~2e -2f 9 + 4a h + 4b i + 4c 2a ~b 4c 2d ~e 4f 29 ~h 4i d 9 h

Step 1
We can add twice the first row to the second row and subtract the first row from the third row: $$ \begin{vmatrix} f & h & -10 \\ 0 & -2e+2h & -2f+20 \\ 2a-f & -b-h & 4c+10 \\ 2d & -e & 4f \\ 29 & -h & 4i \\ d & 9 & h \end{vmatrix} $$ Show more…

Compute the determinant of each of the following matrices: (a) $A=\left[\begin{array}{lll}2 & 3 & 4 \\ 5 & 6 & 7 \\ 8 & 9 & 1\end{array}\right]$ (b) $B=\left[\begin{array}{rrrr}4 & -6 & 8 & 9 \\ 0 & -2 & 7 & -3 \\ 0 & 0 & 5 & 6 \\ 0 & 0 & 0 & 3\end{array}\right]$ (c) $\quad C=\left[\begin{array}{rrr}\frac{1}{2} & -1 & -\frac{1}{3} \\ \frac{3}{4} & \frac{1}{2} & -1 \\ 1 & -4 & 1\end{array}\right]$
Compute the determinant of the matrix A below by using row operations to transform A into an upper-triangular matrix B. Then express the determinant of A as a multiple k of the determinant of B and use this to compute the determinant of A. det(A) = k * det(B)
