Answer:
130
Step-by-step explanation:
You want the determinant of the matrix ...
![\left[\begin{array}{ccc}4&3&2\\-3&1&5\\-1&-4&3\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D4%263%262%5C%5C-3%261%265%5C%5C-1%26-4%263%5Cend%7Barray%7D%5Cright%5D)
One way to figure it is as the difference between the sum of products of the down-diagonals and the sum of products of the up-diagonals:
D = (4)(1)(3) +(3)(5)(-1) +(2)(-3)(-4) -(-1)(1)(2) -(-4)(5)(4) -(3)(-3)(3)
= 12 -15 +24 +2 +80 +27
D = 130
The determinant of the coefficient matrix is 130.

Answer:
Deez
Step-by-step explanation:ok so you start with deez and then multiply that by the coefficient and got get nuts
For this case we have the following expression:
7 × 10 = 70
Where, by definition:
7: multiplying
10: multiplier
By definition we have that the multiplier equals the number of times the multiplicand must be added.
Therefore, 7 * 10 is to add 10 times 7:
7 * 10 = 7 + 7 + 7 + 7 + 7 + 7 + 7 + 7 + 7 + 7 = 70
Answer:
Multiplier
