Two of the parallel sides of the plane will each equal NP  = 6

The  other two parallel sides will each equal PU  =  sqrt ( 6^2 + 15^2)  =  sqrt (36 + 225) =

sqrt ( 261)

So.....the perimeter  of NPUR  =  2 [ 6 + sqrt (261) ] ≈ 44.3 ft

This is it, thank you! =)

Forgot I was adding 5 instead of subtracting 5! 

5/(1+x) = 3 – 4/(x-1)

Answer is suppost to be

x1 = -0,21

x2 = 3,21

Where did I go wrong? :D

\(\frac{5}{1+x}=3-\frac{4}{x-1}\)

\(\frac{5}{1+x}+\frac{4}{x-1}=3\)

\(\frac{5x-5+4+4x}{x^2-1}=3\)

\({9x-1}=3x^2-3\)

\(3x^2-9x-2=0\)

\(x^2-3x-\frac{2}{3}=0\)

\(x_1=1.5+\sqrt{2.25+\frac{2}{3}}\)

\(x=1.5\pm\sqrt{2.91\overline{66}}\)

\(x_1=3.2078\\x_2=-0.2078\)

Solve for x:
5/(x + 1) = 3 - 4/(x - 1)

Bring 3 - 4/(x - 1) together using the common denominator x - 1:
5/(x + 1) = (3 x - 7)/(x - 1)

Cross multiply:
5 (x - 1) = (x + 1) (3 x - 7)

Expand out terms of the left hand side:
5 x - 5 = (x + 1) (3 x - 7)

Expand out terms of the right hand side:
5 x - 5 = 3 x^2 - 4 x - 7

Subtract 3 x^2 - 4 x - 7 from both sides:
-3 x^2 + 9 x + 2 = 0

Divide both sides by -3:
x^2 - 3 x - 2/3 = 0

Add 2/3 to both sides:
x^2 - 3 x = 2/3

Add 9/4 to both sides:
x^2 - 3 x + 9/4 = 35/12

Write the left hand side as a square:
(x - 3/2)^2 = 35/12

Take the square root of both sides:
x - 3/2 = sqrt(35/3)/2 or x - 3/2 = -sqrt(35/3)/2

Add 3/2 to both sides:
x = 3/2 + sqrt(35/3)/2 or x - 3/2 = -sqrt(35/3)/2

Add 3/2 to both sides:
Answer: | x = 3/2 + sqrt(35/3)/2         or          x = 3/2 - sqrt(35/3)/2

thankyou so much this helped a lot 

Hey, Rosie! I'm doing great, what about you?  One thing I have planned for summer break is going to Utah to visit my mom's side of the family.

Now, here's a question for you. What do you like to do in your spare time and what are you planning to do this week or next week?

Stay Awesome!

Hey, Rosie, is that your favorite cat? And, thanks for spreading the positivity.

Stay Awesome!

-MagikalRedNiteTiger

Ah right!

Thank you once again!

It's an OYSTER Rosie!

Thanks!

Note that  1  = 3^0    ....so we have

3^(2 - 2x)  =  3^0      since the bases are the same, we can solve for the exponents

2 - 2x  = 0        add 2x to both sides

2  = 2x             divide both sides by 2

1  = x

I ma in 3rd grade and I can do this problem it's sqrt(2)*8 because 128 is 2^8. it is 8sqrt2

An

O - Y - S - T - E - R........!!!!!

OYSTER

Thanks for that, Rosy.......!!!!

Note  what happens when we expand   (x + 0.5) ( x - 6.5)

Distribute the terms in the first set of parentheses over the terms in the second set

x ( x - 6.5)  +  0.5 ( x - 6.5)   =

x^2  - 6.5x  + 0.5x - 3.25        combine like terms

x^2  - 6x  -  3.25

Now just apply the (-4/13)  over these to get the final function

Hope that helps and lemme know if you need anything else.

Press [MODE] and put the calculator in SEQ mode. To highlight an item in the Mode menu, use the arrow keys to place the cursor on the item, and then press [ENTER]. Highlight SEQ in the fifth line to put the calculator inSequence mode. 

To cite my source I used google 

Aight cool, thanks!

Just one last question, where does the 6x come from?

Isn't 2x*0,5 just 1? :o 

Note that   g(x)  =  - 2  / (-x - 3) +5    can be written as   g(x)  =  - 2  / - (x + 3) + 5 =  

2 / (x + 3)  + 5

The   (x + 3)  part  shifts the graph of   1/x   to the left by 3 units

The "2"   vertically stetches the parent graph by a factor of 2

Additionally, the "+5"  shifts the parent graph up 5 units 

So  putting all these together......the parent function is shited to the left by 3 untis, up by 5 units and vertically stretched by 2 units

See  the graphs of   1/x  , 2/x , 2/ (x + 3) and  2 /( x + 3) + 5  here :

I just want to know how to use the "sequence mode" in a regular calc.. :/

thanks
