did you try drawing a picture?
anonymous
  • anonymous
what's the area of a triangle in terms of height and base?
anonymous
  • anonymous
actually you dont really need a picture A=1/2b*h

Ok so what's next?
anonymous
  • anonymous
so you have an equation for b and h
anonymous
  • anonymous
you need one more equation, since you have two unknowns.
anonymous
  • anonymous
Ok..
anonymous
  • anonymous
"a height 10ft greater than it's base." try to write an equation based on that statement
anonymous
  • anonymous
I have no clue lol
anonymous
  • anonymous
i get lost on these problems
anonymous
  • anonymous
if b is 6 what is h?
anonymous
  • anonymous
10
anonymous
  • anonymous
because 10 is 10 more than 6?
anonymous
  • anonymous
yes
anonymous
  • anonymous
what's 6 plus 10
anonymous
  • anonymous
16
anonymous
  • anonymous
so 16 is 10 more than 6
anonymous
  • anonymous
if b=6 h=16
anonymous
  • anonymous
if b=7 h=?
anonymous
  • anonymous
16
anonymous
  • anonymous
?
anonymous
  • anonymous
because 16 is 10 more than 7...
anonymous
  • anonymous
so my answer is 7, 16
anonymous
  • anonymous
this was fun.
anonymous
  • anonymous
the computer again said that was wrong?
anonymous
  • anonymous
??

anonymous
  • anonymous
so what is my answer?
anonymous
  • anonymous
for the base and heig
anonymous
  • anonymous
t?
anonymous
  • anonymous
You have to solve for x.
anonymous
  • anonymous
X(x+10) / 2??
anonymous
  • anonymous
now?

Good job Denebel. KE, if you can't follow simple instructions, nobody will help you. Nobody is just going to post the answer.
anonymous
  • anonymous
\[72=\frac{ 1 }{ 2 }x(x+h)\] Do you know how to solve for x?
anonymous
  • anonymous
Yes but it comes out to be like a square root.. I'm not stupid or anything
anonymous
  • anonymous
prove it.
anonymous
  • anonymous
prove what?
anonymous
  • anonymous
wow.
anonymous
  • anonymous
Um excuse me Mrs. wrong answer giver Algebraic I can block u also...
anonymous
  • anonymous
Ok, what did you do so far?
anonymous
  • anonymous
when I divided the equation u told me to divide i got 2 big square roots
anonymous
  • anonymous
? Can you show me the steps? Draw or write it out.
anonymous
  • anonymous
I'm not even sure if i worked it right? I put it in my calcuator
anonymous
  • anonymous
If you don't mind me asking, what math are you taking?
anonymous
  • anonymous
Intermediate.
anonymous
  • anonymous
Is there a particular subject? On the cover of your textbook? Have you learned about distribution?
anonymous
  • anonymous
Also, how did you type x(x+10) in your calculator...
anonymous
  • anonymous
Have u ever used a graphing calucator?? u can type that in to that
anonymous
  • anonymous
what did you get for a base?
anonymous
  • anonymous
Yes the particular subject is intermediate math i believe i said that
anonymous
  • anonymous
I don't even know now people are making me mad on here tonight
anonymous
  • anonymous
well assuming you have a graphing calculator i put down (1/2)(x(x+10))-72 find when y=0 and got x=8
anonymous
  • anonymous
ok
anonymous
  • anonymous
sorry for above shouldve check this sooner
anonymous
  • anonymous
huh?
anonymous
  • anonymous
|dw:1347075231860:dw|
anonymous
  • anonymous
duh ok i already knew that.... ...... but is that my base or height????
anonymous
  • anonymous
It's nothing, you have to solve for x first. It's just an equation so you find your base and height.
anonymous
  • anonymous
Ok did i just not solve this same one though?
anonymous
  • anonymous
Which other equation did you solve?
anonymous
  • anonymous
I thought i just solved this one
anonymous
  • anonymous
x=-18,8 ???? is that right
anonymous
  • anonymous
well the base cant be negative so just x=8
anonymous
  • anonymous
Measurements of an object can be negative. |dw:1347075538826:dw|
anonymous
  • anonymous
so my base is 8 and my height is -18???
anonymous
  • anonymous
so much fail.
anonymous
  • anonymous
what?
anonymous
  • anonymous
Oops typo there, I mean CAN'T
anonymous
  • anonymous
Denebel u have me lost...
anonymous
  • anonymous
the height was 10 more than the base if the base if 8 8+10 =18 case closed
anonymous
  • anonymous
so my base is 18 and my height is 10?
anonymous
  • anonymous
@completeidiot Also has to satisfy A=72
anonymous
  • anonymous
no... base is 8 height is 18...... 8*18=144 144/2=72 GAHHHHHHHH
anonymous
  • anonymous
Oops sorry My brain is wacked. I typed it in my calculator wrong.
anonymous
  • anonymous
LOL Yes @KE8717504 , completeidiot is correct
anonymous
  • anonymous
THANK YOU SO MUCH @completeidiot
anonymous
  • anonymous
@Denebel i'm starting to wonder if u know what ur doing.. and u are very confusing.
