22 done by: Shannon Wissel i think you messed up the signs a little bit so that would make your answer wrong but your work looks good. All of your answers should be positive insead of <-+-> otherwise your answer is correct Checked by: Leslie Baker

I got same answers except 30 can be simplified to 3sqrt30! Checked by Jennifer Hassell

Done by Jan Dudek I got the same thing! Good Job! Checked by Ellen Barth

20. I dont have a scanner, but the answer I got is x + y - 4z + 9 = 0. I got -6i - 6j + 24k from my work and put it in the equation along with the points (4, -1, 3) and thats how I got my answer, not sure if its right though. Done by Fred Jordan

Well, I also got to -6i - 6j + 24k and i also put it in the equation with the same points, (4, -1, 3), but I ended up getting x - y - 4z + 7 = 0 Checked by Joon Baek

22. Done By: Courtney Venable Hey court, your set up is correct until you solve your determinants. You accidentally added instead of subtracted (the formula is ad-bc) which threw off your answer from there. The correct work would be Checked by Emily Johnson
