Answer: 24-10√5

Answer 1

i will tell you if you show me every step you did to reach that answer:)

Answer 2

I found the answer to this, thank you :)

Answer 3

I have another one though, I'll show you how I got it :)

Answer 4

ok:) nice
ill wait for it

Answer 5

Thanks!!! :)

Answer 6

Which of the following is a solution to

√x + 10 + 8 = 3

My answer: -5

How? √-5 + 10 + 8 = 3.60555127546

Answer 7

what are the other options you have?

Answer 8

x = 15

x = 5

x = -5

x = -15

Answer 9

why do you think this: How? √-5 + 10 + 8 = 3.60555127546 proves that -5 is the solution to √x + 10 + 8 = 3?
since you have to find a solution for √x + 10 + 8 = 3 you have to solve it for x.

Answer 10

try to solve the equation for x

Answer 11

I saw the three, and figured the rest would be cut off. Now i see how irrational it sounds.

Answer 12

15,-15,5 and -5 are all the options you have?

Answer 13

Yes

Answer 14

OH1 It would be a positive, so that narrows it down

Answer 15

hmm well my answer would be i*sqrt(15) but there is no such choice....have they tought you the imaginary numbers yet?

Answer 16

That's what I just got, the fifteen, but calculated there's a big number that doesn't even have the three in place

Answer 17

it has been addressed briefly

Answer 18

no w8 i got it wrong ...give me a sec

Answer 19

I did another problem just like it, and got one solid answer

Answer 20

did you get 225?

Answer 21

have to restart my modem brb!

Answer 22

ok!

Answer 23

a question!: maybe the equation is not √x + 10 + 8 = 3 but √(x + 10) + 8 = 3? because like this it would make sence

Answer 24

Let me check

Answer 25

It's still the former

Answer 26

√x + 10 = 3

Answer 27

without 8?

Answer 28

OOPS!!!!!! wrong wrong wrong!

Answer 29

√x + 10 = 8 = 3

Answer 30

write it again

Answer 31

Honestly none of them seem to work

Answer 32

Sorry i pressed the equal sign twice, my apologies

Answer 33

√x + 10 + 8 = 3

Answer 34

considering it equals a positive three, the only option are A and B, so I'm going with the former

Answer 35

i dont understand your way of deciding the answer...

Answer 36

It makes sense by what I have on my paper, I'm sorry

Answer 37

you dont have to be sry...im just curious myself:)

Answer 38

process of elimination, dear

Answer 39

I see the three, that's better than getting an answer that's not even in the problem that GIVES you the answer (it being 3)

also, it's a positive three

Although it makes little to no sense, that's the way to go because there's either an error in the whole problem, or I'm reading too into it

Answer 40

i can tell you that if the equation were:
√(x + 10) + 8 = 3 then:
√(x + 10) = 3-8
√(x + 10) = -5
√(x + 10) =√((-5)^2)
x+10=(-5)^2
x+10=25
x=25-10
x=15

Answer 41

anyway , when you know the right answer please let me know about it!:)GL with it!

Answer 42

thanks!!!!!!! :) i will :) @MicroBot
