Answer:
Step-by-step explanation:
You have to group all of the same one's together and however many there is, you add that number as the exponent.
There were 2 "(-2)" so that became , and there were 5 "7" so that became
. You keep the symbol and put it together which became
the distance form X to Y is clearly -6 to 0 is 6 units, and 0 to 8 is 8 units, so 6 + 8 = 14 units.
now, for XZ and ZY we can simply use as stated, the distance formula to get those and then add them all to get the perimeter.
Answer:
0
Step-by-step explanation:
Use discramnt formula
Where 6 is a, 11 is b and 9 is c
Since the discramnt is negative, there are no real solutions and it will only produce imaginary solutions
