X= -4
...,...................
We need to use distance formula
Distance=√((x2-x1)²+(y2-y1)²)
Distance=√((7-5)²+(3-(-1))²)=√(4+16)=√20=2√5≈4.47
Answer:
20 weeks is your answer because you decide by time I think
2n - 5 = 7
Add 5 to both sides.
-5 + 5 = 0
7 + 5 = 12
2n = 12
Divide both sides by 2.
2n / 2 = n
12 / 2 = 6
n = 6.
Your answer is 6.
I hope this helps!
