The area of a tiled kitchen floor is represented by the expression 4x2 + 24x + 27, where x represents the length of a single til e. The length, l, of the floor is 9 feet more than twice the length of a tile, x. Which expression represents the width of the kitchen in terms of x?
2 answers:
The correct answer should be "2x + 3".
Let x--------> <span>represents the length of a single tile L-------> t</span><span>he length of the floor W------> the</span><span> width of the floor A--------> </span>area of a tiled kitchen floor <span> we know that A=W*L A=</span>4x²<span> + 24x + 27 </span>so W*L=4x² + 24x + 27---------> equation 1 L=2x+9------> equation 2 substitute equation 2 in equation 1 W*[2x+9]=4x² + 24x + 27 W=[4x² + 24x + 27]/[2x+9] thereforethe answer is the <span>expression that represents the width of the kitchen in terms of x is </span>W=[4x² + 24x + 27]/[2x+9]
