## anonymous 4 years ago Base and height of triangle whose height is four more than seven times its base. Whats the base and height? Thanks :)

1. anonymous

h = 7a + 4 a = (h-4)/7

2. anonymous

whats the seven?

height is four more than 7 times its base so h= 7b+4 where b is base so 7b=h-4 b=(h-4)/7

4. anonymous

/7 is what i meant :) but thank you for that information

7 is given in the question :) "seven times its base " :)

6. anonymous

How do i get the answers, do i solve both?

i hope this is the final answer

8. anonymous

which one is the final answer :) is the answer just how its set up?

$h= 7b+4$$b= \frac{(h-4)}{7}$

Thank you :) Can you help me with two more? Then I'll be done for now. I'm just on a less time because I got up late and I have to work on another project soon. But first I have to get this math out of the way, my teacher makes us have perfectly correct answers

I'll try

wait 5min

ok :D thanks so much, ill be right back...

one leg of a right triangle is 6 millimeters shorter than longer leg, and hypotenuse is 6 millimeters longer than longer leg. Find lengths of sides of triangle.

15. anonymous

so i need longer, shorter, and hypo :)

Longleg=x shorter leg= x-6 Hypo=x+6 (x+6)^2=(x-6)^2+x^2 x^2+12x+36=x^2-12x+36+x^2 x^2-24x=0 x(x-24)=0 x=0 or x=24

17. anonymous

Yay thanks so much! One more question and I'm done...be right back :D

ok :)

19. anonymous

oh which is longer etc?

20. anonymous

i've , mentioned everything can you tell me which is longer , shorter & hypotenuse?

22. anonymous

hypo: 30 longer:24 short:19?

is short one 19?

24-6=18 :)

25. anonymous

18? ok thanks :D Ill be back in a sec

26. anonymous

Ok same problem but 1 mill instead of six :( My computer kicked me off and made me a new problem, I'm sorry

i didnt get you,what happend?

28. anonymous

The problem reset

29. anonymous

can you solve it with 1 instead of six used? mill wise :)

31. anonymous

ok just a sec :)

32. anonymous

I tried :( I just messed the whole thing up, the dumb x^2 confuses me

(x+1)^2=(x-1)^2+x^2 x^2+2x+1=x^2-2x+1+x^2 x^2-4x=0 x(x-4)=0 x=0 or x=4 longest=4 shortest =4-1=3 hypo=4+1=5

34. anonymous

oh Diya thanks so much :)

Welcome =)

I have one more now ^_^ <3
