Answer:
is reasonable.
is not reasonable, because the volume of the shipping box can't be negative.
Step-by-step explanation:
1. Apply the Distributive property to the given equation. Then, you have:
2. You obtain a quadratic equation, then you can use the quadratic formula to solve it:
3. Then, you obtain:
4. The volume of the shipping box can't be negative. Therefore, is reasonable and
is not reasonable.
The values represent the robot facing east, south, and west are 1, -i, -1.
<h3>What was the meaning of puzzle?</h3>To offer or represent to (someone) a problem difficult to solve or a situation difficult to resolve : challenge mentally also : to exert (oneself, one's mind, etc.) over such a problem or situation they puzzled their wits to find a solution.
given that,
The robot can only go north, south, east and west.
Assuming that the north-south axis corresponds to the y-axis and west-east axis corresponds to x-axis.
Now,
It is provided that the ' i ' represent that robot is facing north.
So, if the robot turns and faces south, it can be seen that he will be facing in the opposite direction of ' i '.
Since, the values on y-axis are negative in that direction.
Hence, South will be represented by ' - i ' .
Moreover, it is given that we use only the numbers whose magnitude is 1. As, west-east axis represents x-axis.
So, the value that represents East will be 1.
(as it is on the positive x-axis ).
Since, west is in the opposite direction of east.
So, West will be represented by -1.
Hence,The values represent the robot facing east, south, and west are 1, -i, -1.
