A square shaped classroom is replacing its floor tiles. If 19 tiles make up each side of the
classroom, how many total tiles willihey need
to buy? If each tile costs $5.95, how much will
it cost to replace the tiles?

361 tiles and $2,147.95

Step-by-step explanation:

19x19 to find tile area

361 x 5.95 to find cost

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.
