\[5^{2}+7^{2}=x^{2} under that is, 25+49=x^{2}, below that is \sqrt{79}=\sqrt{x}^{^{2}} what does x^{2}=?\] & thanks ^.^

I wish I could show a pic, it's Pythagonean and Theorem.
hartnn
  • hartnn
you want to learn pythagoras theorem or u want to know how \(x=\sqrt{79}\) ??
hartnn
  • hartnn
and x^2 = 25+49 = 74
hartnn
  • hartnn
not 79
anonymous
  • anonymous
Sorry I meant 74, but I wanted to know the answer to it because there are 4 answers, 1)6.3 2)7.1 3)14.1 & 4)17.1
hartnn
  • hartnn
then u need to post the entire question clearly....
hartnn
  • hartnn
because sqrt 74 = 8.6

The end of the dog's leash is attached to the top of a 5-foot-tall fence post, as shown in the diagram below (this is where the equation is) The dog is 7 feet away from the base of the fence post.

|dw:1356724058436:dw| whats need to be found ?
hartnn
  • hartnn
if x is to be found, its 8.6

Okay thanks, how about the legs of an isosceles right triangle each measure 10 inches. WHat is the length of the hypothesis of this triangle, to the nearest tenth of an inch?
hartnn
  • hartnn
again pythagoras theorem |dw:1356724579218:dw|

Answers are 6.3,7.1,14.1, and 17.1 Would it be 14.1?
hartnn
  • hartnn
yes :) did u understand how ?
anonymous
  • anonymous
Lol no honestly, I need help, it was just a lucky guess for me because I knew the answer had to have a four in it right?
hartnn
  • hartnn
For any right angled triangle, |dw:1356724844491:dw|
hartnn
  • hartnn
did u get that ?
hartnn
  • hartnn
u had a=b=10 \(c^2=10^2+10^2=200 \\ c=\sqrt{200}=14.1\)
hartnn
  • hartnn
which part u have doubt with ??
anonymous
  • anonymous
Oh okay I see now thanks :) What is the value of x? \[13x-2(x+4)=8x+1\]
anonymous
  • anonymous
So then I would start with 11x-2x+8=8x+1 right?
anonymous
  • anonymous
Then add 2x to both sides? 2x+2x, 2x+8x
hartnn
  • hartnn
-2(4)=-8 and not +8
anonymous
  • anonymous
I'm lost at this part 11x-2x+8=8x+1 +2x +2x 11x+8=10x+1 -10x -10x?
hartnn
  • hartnn
sorry, got disconnected \(13x-2(x+4)=8x+1 \\ 13x-2x\large \color{red}{+8}=8x+1 \\11x+8=8x+1 \\ 11x-8x =1-7 \\ 3x=-6 \\x=....?\) ask if there is any doubt in any step...
anonymous
  • anonymous
I get it so the answer would be 2?
anonymous
  • anonymous
If 3(x+2)-2(x+1)=8 the value of x is? I need help pls.
hartnn
  • hartnn
sorry, i did the same mistake again \(13x-2(x+4)=8x+1 \\ 13x-2x\large \color{red}{-8}=8x+1 \\11x-8=8x+1 \\ 11x-8x =1+8 \\ 3x=9 \\x=3\)
anonymous
  • anonymous
It's okay :)
anonymous
  • anonymous
would be 4 right?
hartnn
  • hartnn
3(x+2)-2(x+1)=8 3x+6-2x-2=8 x+4=4 x=4 yes :)
hartnn
  • hartnn
*x+4=8
anonymous
  • anonymous
Wait for that last one wouldn't it be 2 because 3 goes into 6 twice?
anonymous
  • anonymous
Pls solve this someone has a container with 4200 millilitre of waters are in someone's container
hartnn
  • hartnn
sorry, i didn't get your doubt ? 3x=9 so, x=3
anonymous
  • anonymous
Oh oh I see sorry lol it looked like a 6 for a minute. thanks. How about Debbie solved a linear equation 3(x+4)-2=16 where did she make an error? Line 1: 3(x+4)-2=16 Line 2: 3(x+4)=18 Line 3: 3x+4=18 Line 4: 3x=14 Line 5: \[4\frac{ 2}{ 3 }\]
anonymous
  • anonymous
Oops sorry Line 5 is suppose to say x= then what I put.
hartnn
  • hartnn
3(x+4)=18 x+4 = 18/3 =6
hartnn
  • hartnn
so, mistake in line 3, while distributing.
hartnn
  • hartnn
if more Q coming up, then close this and ask it in a new post...
anonymous
  • anonymous
Okay thanks.
hartnn
  • hartnn
