bonus #1

6. anonymous

7. anonymous

ok u want do bonus question 1?

8. anonymous

yes plz

9. anonymous

3x^2+5x-1=0 x=(-5+-sqrt(25+4))/6 now simplify

10. anonymous

$\frac{-5\pm \sqrt{5^{2}-4(3\times (-1)}}{(2\times3)} =\frac{-5\pm \sqrt{25+12}}{6}$

11. anonymous

OK , bye

12. anonymous

bye

13. anonymous

i need help with 2 more problems

14. anonymous

Which questions do you need help on?

15. anonymous

16. anonymous

number 18 on this one

17. anonymous

Ok opposite sides of a paralleogram are equal in length so make to equations y2 = 49 so y = 7 (answer) Other equation x + 9 = 4x - 27 subtract x from each side 9 = 3x - 27 Add 27 to each side 18 = 3x divide each side by 3 x = 6 *answer()

18. anonymous

can u show me a break down of the first one plz

19. anonymous

20. anonymous

One side of the parallelogram is y squared and the other is 49 They are equal in length so if we take the sq root of both of them y = 7

21. anonymous

how u got the answer because i dont get it im confused

22. anonymous

oh we are dividing

23. anonymous

No we are finding the square root of 49 and of y squared because they are equal

24. anonymous

wait are we doing number 18 or bonus number 2

25. anonymous

ohh we have to solve twice

26. anonymous

thats where i got confused
