    5. If A(5, 5), B(3, 3), C(6, 8), and D(-3, 4), what is the length of AB? Round to the nearest tenth. (Points : 1) Question 6. 6. If A(5, 5), B(3, 3), C(6, 8), and D(-3, 4), what is the length of BC? Round to the nearest tenth. (Points : 1) Question 7. 7. If A(5, 5), B(3, 3), C(6, 8), and D(-3, 4), what is the length of CD? Round to the nearest tenth. (Points : 1)

    Distance formula is \[d=\sqrt{(x _{2}-x _{1})^2+(y_{2}-y_{1})^2}\]

    Just take the x's and y's of the two points and plug them in to find the distance between them :)

    Just plug the values into the formula I provided. The equation with the larger x will be the x2 and y2 equation.

    So we're trying to find the distance between A and B. A is (5,5) and B is (3,3). Since 5 is greater than 3, A is going to be our x2, y2 equation and B is our x1, x2 equation. Now we just plug them into the formula. \[d=\sqrt{(5-3)^2+(5-3)^2}\] Solve the parentheses \[d=\sqrt{(2)^2+(2)^2}\] Find the square of it\[d=\sqrt{4+4}\]Add\[d=\sqrt{8}\] Since we're rounding to the nearest hundredth, that means that we're just gonna plug this into a calculator to find the result.

    How about this? You set up the second one and if I need to, I'll correct you and help you through #6. After that, you do #7 on your own

    How in the world are you getting 28? And are you not paying attention to my posts? I'm helping you through it. I am seriously confused as to how you're getting 28

    Right now we have this\[d=\sqrt{(3*3)+(5*5)}\] Can you solve the parentheses?
