The first odd number before 231 which would be on the same side of the hall is 229. The first odd number after would be 233.
On the odd side of the hall, the order would be room 229, room 231, room 233.
183 is the answer to that
Answer:
The answer to part A is 15 cm because you would first divide 16 by two to find the base of one triangle. Then you would do the pythagorean theorem to find the height. <em> I don't know if that would help.</em>
The answer to part B is 240 cm squared because you would find the area of one right triangle and multiply it by 4 to find the area of all the sides of the box.

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.

Many scientific and graphing calculators and web sites can perform this calculation for you.
It’s four because you subtract 2 minus negative 2
