Answer:
Can' possible......
Step-by-step explanation:
Let suppose the numbers are:
x
x + 1
x + 2
Now according to given condition:
x + x +1 + x+ 2 = -206
By adding we get:
3x + 3 = -206 Subtracting 3 from both sides:
3x + 3 - 3 = -206 -3
Both terms on right side have negative sign so we will add them. (answer will have negative sign.)
3x = -209
Dividing both sides by 3:
x = -209/3
x = -69.6666
that is not an integer so the question is wrong.
I hope it will help you!
Answer:
-4/3
Step-by-step explanation:
first we can name this number x
so then our equation would be
3+6x=-5
then subtract 3 from both sides
6x=-8
divide both sides 6
x=-8/6
simplify
x=-4/3
Answer:

Step-by-step explanation:
Given
![A = \left[\begin{array}{cc}-2&6\\3&5\end{array}\right]](https://tex.z-dn.net/?f=A%20%3D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D-2%266%5C%5C3%265%5Cend%7Barray%7D%5Cright%5D)

Determine the determinant
For a two by two matrix, A such that:
![A = \left[\begin{array}{cc}a&b\\c&d\end{array}\right]](https://tex.z-dn.net/?f=A%20%3D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7Da%26b%5C%5Cc%26d%5Cend%7Barray%7D%5Cright%5D)
The determinant |A| is:

So, in
![A = \left[\begin{array}{cc}-2&6\\3&5\end{array}\right]](https://tex.z-dn.net/?f=A%20%3D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D-2%266%5C%5C3%265%5Cend%7Barray%7D%5Cright%5D)
The determinant is:
