help @jonnyy9

OpenStudy (briannabug):

Whats the question?

OpenStudy (anonymous):

um

jhonyy9 (jhonyy9):

i m here

OpenStudy (anonymous):

\[3+\sqrt{x+19}-\sqrt{2} when x=6\]

jhonyy9 (jhonyy9):

so 3 + sqrt(x+19) -sqrt2 = ? for x=6 --- yes ?

OpenStudy (anonymous):

yes

jhonyy9 (jhonyy9):

substittute the 6 in place of x inside sqrt

OpenStudy (anonymous):

can u show me how to do it the hole thing

jhonyy9 (jhonyy9):

yes but you need cooperate and make what i have said to you - ok. ?

OpenStudy (anonymous):

ok

jhonyy9 (jhonyy9):

sqrt(x+19) = ? when x=6

OpenStudy (anonymous):

25

jhonyy9 (jhonyy9):

yes nice so sqrt25 = ?

OpenStudy (anonymous):

5

jhonyy9 (jhonyy9):

exactly

OpenStudy (anonymous):

then what

jhonyy9 (jhonyy9):

so use this result above in your exercise - can using it there ?

OpenStudy (anonymous):

so 3+\[\sqrt{5}-2\]

jhonyy9 (jhonyy9):

3 + sqrt(x+19) -sqrt2 = ? for x=6 --- yes ? in place of sqrt(x+19) you can writing 5 - yes ?

OpenStudy (anonymous):

yea

jhonyy9 (jhonyy9):

why you have wrote there sqrt5 ?

jhonyy9 (jhonyy9):

this is just 5 without sqrt

OpenStudy (anonymous):

ook

OpenStudy (anonymous):

then what solve

jhonyy9 (jhonyy9):

how will be than your equation now ?

OpenStudy (anonymous):

3+5-2

OpenStudy (anonymous):

the answer is 6 right

jhonyy9 (jhonyy9):

3+5 -sqrt2 = ? sqrt2 how you eliminate ?

OpenStudy (anonymous):

idk um

jhonyy9 (jhonyy9):

sqrt2 is different term than 3 and 5 so you not can doing with nothing just assum 3 with 5 and what will get ?

OpenStudy (anonymous):

8

jhonyy9 (jhonyy9):

3+5 = ?

jhonyy9 (jhonyy9):

yes so rewrite your equation how is now ?

OpenStudy (anonymous):

\[8-\sqrt{2}\]

jhonyy9 (jhonyy9):

make it equal zero and assum to both sides sqrt2 so what will get ?

OpenStudy (anonymous):

idk what u are saying can u show me

jhonyy9 (jhonyy9):

8-sqrt2 +sqrt2=0+sqrt2 - do you understand it now ?

OpenStudy (anonymous):

ok kind of

jhonyy9 (jhonyy9):

so than make the calculi

OpenStudy (anonymous):

i am still confeused

jhonyy9 (jhonyy9):

-sqrt2 +sqrt2 = ? and 0 + sqrt2 = ?

OpenStudy (anonymous):

how would i solve that

jhonyy9 (jhonyy9):

- 1 +1 = ?

OpenStudy (anonymous):

1

OpenStudy (anonymous):

right

jhonyy9 (jhonyy9):

no

OpenStudy (anonymous):

o

jhonyy9 (jhonyy9):

yes zero

OpenStudy (anonymous):

ok then what

jhonyy9 (jhonyy9):

so in the left side what will remain there ?

OpenStudy (anonymous):

2

OpenStudy (anonymous):

no 8

jhonyy9 (jhonyy9):

8-sqrt2 +sqrt2=0+sqrt2 - do you understand it now ? yes 8 and on the right side ?

OpenStudy (anonymous):

3

jhonyy9 (jhonyy9):

what is this 3 ?

jhonyy9 (jhonyy9):

on the right side there are 0+sqt2

OpenStudy (anonymous):

there are 2 answers

OpenStudy (anonymous):

there is

OpenStudy (anonymous):

\[8\sqrt{3}\]

OpenStudy (anonymous):

and

OpenStudy (anonymous):

\[8-2\sqrt{3}\]

jhonyy9 (jhonyy9):

please answer my question

OpenStudy (anonymous):

yea

jhonyy9 (jhonyy9):

so on the left side will get 8 and on the right side what will remain there ? there are 0+sqrt2

OpenStudy (anonymous):

yea and

OpenStudy (anonymous):

so then what

jhonyy9 (jhonyy9):

ok sorry i have checked it above newly and you have got the right answer there above 8-sqrt2 will be ok. ?

OpenStudy (anonymous):

ok but that answeris not there

jhonyy9 (jhonyy9):

because you need just to calculi the value of this equation for x=6

OpenStudy (anonymous):

3 and 2

jhonyy9 (jhonyy9):

so this mean that your exercise not is just what you have wrote there above - how is the text exactly ?

OpenStudy (anonymous):

u mean theanswer

jhonyy9 (jhonyy9):

3+sqrt(x+19) −√2 when x=6 you have wrote there above this

jhonyy9 (jhonyy9):

so for x=6 you have got this equal 8-sqrt2 yes ?

OpenStudy (anonymous):

so would the answer be

jhonyy9 (jhonyy9):

yes that s all

OpenStudy (anonymous):

\[8-2\sqrt{3}\]

jhonyy9 (jhonyy9):

nojust 8-sqrt2 how you get this 2sqrt3 ?

jhonyy9 (jhonyy9):

are you here again ?

OpenStudy (anonymous):

its a answer

jhonyy9 (jhonyy9):

indifferent you have got 8-sqrt2 this is the right answer sure

jhonyy9 (jhonyy9):

ok. ?

jhonyy9 (jhonyy9):

so good luck was my pleasure bye

OpenStudy (anonymous):

ok what was the answer

OpenStudy (anonymous):

thats not there

OpenStudy (anonymous):

bro

OpenStudy (agent0smith):

lol bro he gave you the correct answer, 8 - √2
