Answer 3

is x under the root or it is 7*sqrt(2)*x - 2?

Answer 4

Answer 5

\[7*\sqrt2*x-2=7*\sqrt2*9-2=63\sqrt2-2\]

Answer 6

He gave you two options, you answered "yup". Which of these is it?

\[7\sqrt{2}*x-2\]\[7\sqrt{2x}-2\]

Answer 7

is question is like this

Answer 8

@itseasy2346 which option exactly you meant by "yup"?

Answer 9

the first one 7√2*x-2

Answer 10

is the expression I wrote you was the one you needed?

Answer 11

ya but isnt the both equations the same?

Answer 12

no

the second will be equal to another value:
\[7*\sqrt{2*9}-2=7*\sqrt18-2\]
since sqrt9 equals 3, we can write \[7*3\sqrt2-2=21\sqrt2-2\]

Answer 13

uh never mind guys I got that answer and thx. :)
