A certain ceiling is made up of tiles. Every square meter of ceiling requires 10.75 tiles. A certain ceiling is made up of tiles. Every square meter of ceiling requires 10.75 tiles. What is the constant of proportionality?

10.75 tiles per square meter

Step-by-step explanation:

Here, we want to get the constant of proportionality

From the question, we are told that every square meter needs 10.75 tiles

The constant of proportionality in this case is thus;

10.75 tiles per square meter

x² + 11x + 18 < 0  

[-11 ± sqrt(121 - 72)]/2 = (-11 ± 7)/2  

solution: (-9, -2)
