not solve, just fill the word in the blank

I need check my answer if I correct

- radar

8, Simplify
4, synthetic division

- radar

seems the choices are too restricted!!

- anonymous

number 10 Synthetisc dubtitution ?

- radar

Not for sure, have you googled those words?

- anonymous

no

- anonymous

you have time look another problem?

- radar

I don't see any on the list that would match "degree"

- radar

I may be of help, what is the probllem?

- anonymous

you want me sent you a lesion degree?

- radar

the degree of an equation depends on the highest exponent of the variable, and there was nothing like that on the list.
What is the next problem?

I have looked it over. Here is what I have come up with:
Let x = longer leg
Let y= shorter leg
then 24-(x+y)= hypotenuse
You with me so far. Ask question now about what I have set up for solving this problem.

- radar

We are told the following:
3x-2y=24-(x+y)+3 Do you see where that come from?

- anonymous

P: x+y+z=24
The given: (3*x)-(2*y)=h+2
I know from here ,But I don't know next

- anonymous

sorry z for hypotenuse
The given: (3*x)-(2*y)=z+2

- radar

O.k I put 3 where it should be 2, my equation should be 3x-2y = 24-x-y +2

- radar

then we would have 4x+3y = 26 That is an equation with two unknowns we need to make another equartion. But first need to fix another mistake.
4x-y=26 Do you see why 4x-y=26 cm????

- anonymous

yes I see

- radar

This means y=4x-26. Problem says it is a right triangle we know that by pythagorem theorem hypotenuse is equal to the square root of the sum of the legs squared or\[\sqrt{x ^{2}+y ^{2}}\]

- radar

we substitute for y and get this:
\[hyp=\sqrt{x ^{2}+(4x-26)^{2}}\]
We also know that the hypotenuse is equal to 24-x-y substituting for y we now have
hypotnuse=24-x-(4x-26)
hyp=-5x+50
\[-5x+50=\sqrt{x ^{2}+(4x-26)^{2}}\]Now we have an equality with one unknown

- radar

The radical should extend completely across\[-5x+50=\sqrt{x ^{2}-(16x ^{2}-208x+676}\]

- anonymous

Arte you still there?

- anonymous

From here I just solve for x?

- radar

square both sides of the equation
\[25x ^{2}-500x+2500=x ^{2}-16x ^{2}-208x+676\]
This thing keeps getting bigger and bigger!!!\[40x ^{2}-292x+1824=0\]
A quadratic that should be solvable lol

- anonymous

Ok. thank I can do from now

- radar

You can divide by 4 and get
\[10x ^{2}-73x+456=0\]

- anonymous

I have one more very quick, can you show me how to write faction on the bottom of the chat, I keep play but I can do it.

- radar

I don't know how to write frac on the equation line, if you google latex you will find the math languate they use here.

- anonymous

on the bottom of the chat window

- anonymous

it say Equation

- anonymous

I see every people write fraction

- radar

loki showed me how, but I forget, if you look at "latex" it will explain it.

- anonymous

it Ok I will ask pepole around, thank you for spend time solve my problem

- anonymous

I have to go now bye

- radar

Ok, somewhere there is an error in the solution as the root is a complex value. I will loolk it over and see where it went wrong.

- radar

There were errors, the final quadratic should appear as:\[8x ^{2}-292x+1824=0\]
When solved, you will find x=8 (longer leg)
substitute x in the y=4x-26=32-26=y
y=6 cm (shorter leg)
24-6-8=10cm the hypotenuse
It checks out.
