Answer:
Step-by-step explanation:
A=2i+3j+4k
B=i-2j+3k
Sum of the vectors:
A + B = 2i+3j+4k + i-2j+3k = 3i + j + 7k
Direction of the sum of the vectors:

For this case we must factor the following expression:

To factor, we must find two numbers that when added together give -7 and when multiplied by -10.
It is observed that there are not two whole numbers that comply with the aforementioned.
Thus, the following equation applies:

Where:

We replace:

So, the roots are:

Answer:

Answer:
90
Step-by-step explanation:
no of total groups = 2+6+4=12
so in total there are 12 groups
each have equal number of members
so the answer is the number that is not a factor of 12
