we are using the distance formula right now and i asked my teacher for help on an equation and this quation had a fraction in it and i don't understand how she got her answer. the question that i need help on is: d= the square root of (4-6)^2+(-2/3-2)^2.
First, combine terms within the parentheses.
(-2)^2 + (-2 2/3)^2 = (-2)^2 + (-8/3)^2
Multiply each term by itself. (Remember that a negative times a negative is always a positive.)
Add the two terms and find the square root of that sum to get d.
I hope this helps. Thanks for asking.
