Answer 2

I know how to do this problem but I am getting the wrong answer for some reason...

Answer 3

lemme rewrite that

Answer 4

why isnt (y-7)^3 on the top?

Answer 5

o nvm

Answer 6

thinking too fast :) is that what you had?

Answer 7

(3x)^2 = 9x^2

Answer 8

no... i had ln [ (3x^2)(y-7)^3 / x^3 ]

Answer 9

yea that's right

Answer 10

except it's 9x^2

Answer 11

it keeps telling me im wrong no matter what i try

Answer 12

ln [ (9x^2)(y-7)^3 / x^3 ]

Answer 13

thats what i have and its telling me im wrong

Answer 14

it reduces to 9(y-7)^3/x

Answer 15

that is still wrong -_-

Answer 16

...webassign is lying

Answer 17

Answer 19
