Answer:

4.5 units

Step-by-step explanation:

The formula given is used to calculate the length of a segment given the coordinates of the endpoints.

let (x₁, y₁ ) = A(-1, 1) and (x₂, y₂ ) = (3,3), then

AB = \sqrt{(3+1)^2+(3-1)^2}

    = \sqrt{4^2+2^2}

    = \sqrt{16+4} = \sqrt{20} ≈ 4.5 ( nearest tenth )

I need help wit one & two please help

23 is less than 25 which means it's closer to 20, so you would round it down to 20. 1.75 is over 0.50, 1/2, so you would round it up to 2. If you multiply 2 and 20 you would get 40.

Number two gets the same explanation just with different numbers.
