Answer:
3 < c < 9
Step-by-step explanation:
The length of a side of a triangle cannot be negative. This eliminates the first and last options.
The addition of two sides of a triangle must be greater than the third side. In this case:
3 + 6 = 9 > c
So, the second option is correct. The third option is not correct, because, for example, c = 8 is possible
y= -x/2 + 1 is the answer
Magnitude = sqrt (4^2 + 4^2 + 1^2) = sqrt 33 Answer
Try thinking about negative numbers~ :D
While this is true for positive integers, say, 5 + 6 =11...
would the sum of -15 and -1 be larger than any of the integers?
