Question

2
Find the distance between
the points A (3.5) and B (78)​

Answer 1

Answer: 74.5

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.

Answer 2

5

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 =
`√((7-3)^2+(8-5)^2)`

=
`√(4^2+3^2)`

=
`√(16+9)` =
`√(25)` = 5
