Great post Paulo, I liked that you explained your answer in a easy way using pythagorean relationship. Although for number 11 i saw that for the pictures both of them have the same hypotenuse. Overall, I liked the video but try to get a link next time.

ReplyDeleteGreat job Paulo. I liked that you changed the colour of the important words. You have a great video and link and you did a good job explaining the questions. But how did you get 3,b)? when I did it my answer was over 1000, I have no clue how I got that. Could you explain that please. Other than that it was a very good post.

ReplyDeleteGood job, Paulo. I liked how you used the pictures from the book. It was really helpful in terms of reference. You could have shown the work for question 3, though.

ReplyDeletePaul, there is a link.. UNDER THE VIDEO.

ReplyDeleteOH, WHOOPS. I forgot to put my work for question 3.. i'll just edit tomorrow and add it ok? :)

thanks paulo! I missed the homework so your post was really helpful!

ReplyDeleteGreat job Paulo. I really like the pictures. Also it looks very neat but for number three you should show your work. Other than that, great job.

ReplyDeletePaulo, great job! But aren't I suppose to do questions 3, 9, 13? Overall your post was great and I really liked the pictures. Next time try adding a link.

ReplyDeleteGood job, Paulo. But you used the wrong formula. You are trying to find a2, not b2. So the formula would be c2-b2=a2, not c2-a2=b2.

ReplyDeleteNice job Paulo! Your post was very good, I liked the pictures you used, but I agree with Julibella, you used the wrong formula, but thats okay, all those formulas can be complicated to remember. Overall, great job!

ReplyDeleteGreat job, Paulo. I liked how you used pictures from the math booklet. The colors also made your post outstanding. Next time, add a link. Other than that, good job.

ReplyDeleteGood Job, very outstanding!
