Answer:
≈ 10.20
Step-by-step explanation:
Calculate the distance using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = A(7, - 3) and (x₂, y₂ ) = B(9, 7)
d = [tex]\sqrt{(9-7)^2+(7+3)^2}[/tex]
= [tex]\sqrt{2^2+10^2}[/tex]
= [tex]\sqrt{4+100}[/tex] = [tex]\sqrt{104}[/tex] ≈ 10.20 ( to 2 dec. places )
