Answer:
B.4.47
Step-by-step explanation:
The equation to calculate the distance between two points is
D=[tex]\sqrt{(x_{1}-y_{1} )^{2}+(x_{2}-y_{2} )^{2 }[/tex]
here
[tex](x_{1},y_{1})=(-1,5)\\(x_{2},y_{2})=(3,7)[/tex]
substituting the values
[tex]\sqrt{(-1-3)^{2}+(5-7)^{2} }[/tex]
[tex]\sqrt{(-4)^{2}+(-2)^{2} }[/tex]
[tex]\sqrt{20}[/tex]
[tex]\sqrt{20}=4.47[/tex]
