## anonymous 5 years ago Using the Distance formula, how would you solve from these two points? What do you do with the radicals? (√2,-7√3), (4√2, 8√3)

1. anonymous

just plug them in and solve

2. anonymous

i get √707 but that's not right

3. anonymous

change in x √2 - 4√2 = -4√2 change in y -7√3 - 8√3 = -15√3 then square them change in x: 32 change in y: 675 add them together you get 707

4. anonymous

try $3\sqrt{77}$

5. anonymous

how did you get that?

6. anonymous

from $\sqrt{2}$ to $4\sqrt{2}$ is $3\sqrt{2}$ and from $-7\sqrt{3}$ to $8\sqrt{3}$ is $15\sqrt{3}$

7. anonymous

square. add them together, and then take the square root

8. anonymous

oh i subtracted wrong

9. anonymous

got it. good luck
