I didn't type the question since its on the photo.
I'm reading that ^
I'll try to solve.
Will you give me a minute?
oops error the question is easy use the pythogoread formula c^2=a^2+b^2 white dr is c westerfield is b and blue is a now we plug in. 144= blue^2 + 13^2 ^ that is already squared for you. ^ that is westerfield. Solve for blue. Do you know how?
on previous one i forgot to square the blue blvd one
Okay. Let me try to solve,alright?
so basically 144=a^2+13^2?
Okay, ty. Let me solve for A now,then.
I got '5' as 'a^2'.
I think your diagram might be wrong tho
How's it wrong?
the longest street is suppose to be the c in the theorem. white dr is sqrt (144)= 12 but westerfield is 13 which is longer.
No, that's how it is on my sheet. That's okay. i can leave it as is.
Good observation, though.
so... would it be '144=5^2+13^2'?
it is wrong either blue is longer. But for sure westerfield is longer.
5^2+13^2=194 nott 144 silly
Oh right i forgot to square it.
Sorry bout that...
wait wait wait..
how did you get 194?
you gave me 194 5^2+13^2 you gave that 25+169=194 You cant solve it until you fix the streets. You need to know the longest street. You cant just pick it. white dr =12 but wester field is 13. 13 should be c or blue but we dont even know what blue is. we can make blue c also to see if it works
Fine, whatever you think is best.
Let's make blue C.
make westerfield c and the numbers work better :) c^2= b^2+b^2 169=144+b^2 ^ wester field 13^2 is given so square it to get 169 ^ white 144 was given and already squared ^ blue now solve :)
This might take a min or 2
solve for b
Is it 5?
I also got that the first time.
5 as the missing value, I mean.
Thank you very much for your assistance.
144 = a^2+13^2 --> a=5^2
no but it did not work out cuzz you said "so... would it be '144=5^2+13^2'?" no 5^2+13^2=25+169 is not 144 what you were actually getting was imaginary result. a 5i. what you did was something like this 144=a^2 +13^2 simplifies to 144=a^2+169 then you subtract 169 from both sides 144-169=a^2 -25=a^2 then you try to take sqrt of -25 but how? you cant take sqrt of negatives. you can but it is out of your scope. Unless they taught you about imaginaries already.
That was a long reply. LOL.
Thanks anyhow. So the final equation would be 169=144+b^2 --> b=5?
@timo86m help please
Yes now you just add up the lengths of the streets to see which is longer route.
westerfield and blue =13+5 = 18 blue to white=5+12=17
there is a one mile difference.
yup :D lol you got ahead of me :) But anyhoo i think this is best.
Nope, you're way ahead of me.
I just did first grade subtraction.
So, how would you state the answer?
joe will run one mile further along his new route
