If the cost of tiling a floor is $1.75 per square foot, how much will it cost to tile a rectangular floor that is 9 feet
by 12 feet?

answer: 40392

step-by-step explanation:

10098 x 4 = 40392

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x

1. a^4+8a^3+24a^2+32a+16

2.y^8+8y^7+28y^6+56y^5+70y^4+56y^3+28y^2+8y+1

3.x^6-3x^4y^2+3x^2y^4-y^6

it's possible to build a triangle with side lengths of 3, 3, and 9.- true ( b.)
