Question

If x is one of the sides of the rectangle with an area of 64 square meters, what is the domain of x?

Answer 1

\[x \times x = 64^2\]
\[x^2 = 64^2\]
\[x=\sqrt{64}\]
\[x=8\]
\[8*8 = 8^2\]

Answer 2

Umm... then what is the domain for x?

Answer 3

@agentzero its not a square

Answer 4

oops you are right my bad

Answer 5

that's what i thought at first, but if the maximum is 64 doesn't that imply that the other side would be 1, but the other side could be a half, which would mean that x could be 128.

Answer 6

hmm yes i have made an error, x is not necessarily an integer is it..

Answer 7

we just have 0<x
