a rectangular rug is placed on a rectangular floor. The width is 4 feet greater than the length, x, of the floor. The width of the rug is 2 feet less than the width of the floor. The length of the rug is 4 feet less than the width of the rug. Which function, R(x),represents the area of the floor not covered by the rug? A- R(x)= x^2-x+4 B-R(x)=2x^2+4x-4 C-R(x)=12x-4 D-R(x)=4x+4
Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance

Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
I really need help understanding this question, it's a word problem, I've had experience with this type of question, but a much simpler one.
