Answer:

5

Step-by-step explanation:

Calculate the distance using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = A(3, 5) and (x₂, y₂ ) = (7, 8)

AB = [tex]\sqrt{(7-3)^2+(8-5)^2}[/tex]

     = [tex]\sqrt{4^2+3^2}[/tex]

     = [tex]\sqrt{16+9}[/tex] = [tex]\sqrt{25}[/tex] = 5

Answer: 74.5

Step-by-step explanation: Whenever you see the words distance or difference in a problem, it means to subtract. So, we know that we need to subtract 3.5 from 78.

78 - 3.5 = 74.5

So, the distance between points A and B is 74.5.
