Question

the label on a can of paint states that it will cover 64 square feet what expression will show the length of a square wall that one can of paint will cover

Answer 1

This is a square, so the length of the sides must be equal.
The area is 64 square feet.
A = s^2
64 = s^2
s = 8

Not sure if this is what you meant, feel free to correct me :)

Answer 2

the anwser choices are 64/2, 64^2, 64 (2), and 64 i cant do the symbol with it but it looks like a check almost

Answer 3

oh
then, the 64 with a check is the correct answer :)
The sign that looks like a check is the square root (radical sign), I also don't know how to put it here (I'm slow)

But the 64 with a check is the same as 8, because 8*8 = 64 :)
Hope that helps

Answer 4

Answer 5
