The coordinate plane shows Line A B.<br> What is the length of the line segment?
Lemur [1.5K]

Answer:

AB = 13 units

Step-by-step explanation:

Calculate the distance d using the distance formula

d = \sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2    }

with (x₁, y₁ ) = B(- 5, 12) and (x₂, y₂ ) = A (0, 0)

d = \sqrt{(0+5)^2+(0-12)^2}

   = \sqrt{5^2+(-12)^2}

   = \sqrt{25+144}

   = \sqrt{169}

   = 13

Write a comparison using to show the relationship between 2/3 and 5/6
Stels [109]
2/3 is equal to 4/6 When multiplied by 2/2. You can do this because 2/2 is still equal to one so it doesn’t change the value, just how it looks
