Question

i need some answers checked

Answer 1

@Angle

Answer 2

\(4^2+x^2=12^2\\
16+x^2=144\\
x^2=128\)

=>\(~11.31\)

Answer 3

what?

Answer 4

@dude ?

Answer 5

@Angle

Answer 6

@Eiwoh2

Answer 7

12.6 is correct :)

Answer 8

yet it's saying it's incorrect...

Answer 9

ohhh how... ok, I'ma need a new calculator or something then
dude was right with 11.3 for that one
sqrt(128) = 11.3
on the other hand sqrt(160)=12.6 which is incorrect

because a^2 + 4^2 = 12^2
means that
a^2 = 144 - 16 = 128 not 160
that was my bad, sorry

Answer 10

for the new question
we have that
\(x^2 + x^2 = 6^2\)
using the pythagorean theorem

this becomes: \(2x^2 = 36\)
so
\(x^2 = 18\)
you can square root 18 and get... ?

Answer 11

it's just saying "math processing error"

Answer 12

@Angle is that a glitch?

Answer 13

hmm have you tried refreshing the page?

Answer 14

I'll repost what I just said without the LaTeX

for the new question
we have that
x^2+x^2=6^2
using the pythagorean theorem

this becomes: 2x^2=36
so
x^2=18
you can square root 18 and get... ?

Answer 15

4.24

Answer 16

there you go :)
rounded to the nearest tenth

Answer 17

i think the answer here is C, am i right?

Answer 18

@Angle

Answer 19

I don't think so?

because
x^2 + 33^2 = 65^2
so
x^2 = 4225 - 3136

Answer 20

33

Answer 21

wait oh I messed up

Answer 22

33^2 = 1089
65^2 = 4225

so
x^2 = 65^2 - 33^2 = 4225 - 1089

Answer 23

square root of 1089 is 33?

Answer 24

yes, but I messed up the order before
I meant to write
x^2 = 65^2 - 33^2 = 4225 - 1089 = 3136

so we want to know the square root of 3136

Answer 25

@Vocaloid

Answer 26

On my phone so it's hard to explain but this is a special case where

Hypotenuse = sqrt(2) times the leg

So to find x you just need to divide the hypotenuse by sqrt(2)

Answer 27

divide by ^2?

Answer 28

6.12?

Answer 29

mhm and square root that

Answer 30

2.47

Answer 31

rounded to the nearest tenth :)

Answer 32

says it's incorrect

Answer 33

wot

Answer 34

says 4.2 is incorrect.

Answer 35

but it's 2.5?

Answer 36

2.47 rounded up is 2.5

Answer 37

*oh.*

Answer 38

10.6?

Answer 39

horizontal is left to right, or x values

F = (-3, -3) has an x value of -3
M = (4, 5) has an x value of 4

so the distance from -3 to 4...

Answer 40

6

Answer 41

i mean, 8

Answer 42

D?

Answer 43

@Angle

Answer 44

not quite...

x^2 + 36^2 = 85^2

Answer 45

49?

Answer 46

x^2 + 1296 = 7225

Answer 47

5929

Answer 48

77

Answer 49

there you go :)

Answer 50

i chose D for this one

Answer 51

great ^_^ I think that's right

Answer 52

sqrt7?

Answer 53

3^2 + 4^2 = x^2
9 + 16 = x^2

Answer 54

25?

Answer 55

@Angle

Answer 56

yo?

Answer 57

@Angle

Answer 58

square root of 25
