Answer: $1980
Step-by-step explanation:
Well, based off of the question being asked, I assume that you will need to pay $11 for 90 square footage of tiling, and then the same for the other square footage of tiling. Therefore your answer will be $1980. If you are looking for the equation, it is (<em>11x90)=990 (990)2 = 1980</em>
you do not need to multiply 11 by 90 again because you already know the answer.
X= 49 because the square root of 49 IS 7. :D

so... notice the example there, with 8
so.. you tell us, what is the relationship then?
