Question

Find the length of GH!

Answer 1

Distance formula is square root of (x2-x1)^2 plus (y2-y1)^2
Which is the square root (6-8)^2 plus (5-9)^2
Which is 4.47
Which is approximately 4.5 hope this helps ;)

Answer 2

A

Explanation:

Calculate the length using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = G(6, 5) and (x₂, y₂ ) = H(8, 9)

GH =
`√((8-6)^2+(9-5)^2)`

=
`√(2^2+4^2)`

=
`√(4+16)`

=
`√(20)` ≈ 4.5 → A
