Answer 5

@Ehsan18 @sdfgsdfgs could u help with a bit more XD sorry

Answer 6

i kept getting variants of 10 for #1 also

Answer 7

what is the distance formula?

Answer 8

it the theorem again

Answer 9

yup !

Answer 10

but i keep getting it wrongggggggg

Answer 11

no just google distance formula!

Answer 12

so 9^2+6^2=x^2 right?

Answer 13

which comes out to 10.8 but thats wrong

Answer 14

Distance formula = √(x2-x2)^2+(y2-y1)^2

Answer 15

whaaaaaaa
i missed that in the lesson

Answer 16

and your points are d:(1,3) and h(9,8).

Answer 17

So, youd have to set up your distance formula as such:

c^2=√(8-1)^2+(9-3)^2

Answer 18

Now, continue to simplify.

Answer 19

is the square root for all of it? ahhhhh i still dont get it

Answer 20

#1 i found online is 9.4

Answer 21

Yes, the square root is prevalent throughout the entire simplification process.

Answer 22

@Ashleyisakitty would #2 be 9.5?
