Let's find the expressions for the length and width of the rectangle. The length (which we will call <em>l</em>) is 2 units less than some undefined number, thus we will use the variable <em>x</em>:
l = x - 2
The width is 4 more than this length:
w = l + 4 = (x - 2) + 4 = x + 2
Now, given that we have the length and width and are looking for the area, we need to multiply these expressions together.
One way to write this would simply be (x + 2)(x - 2). If we wanted to find a different way of writing the area, we could use FOIL to find all terms and get x^2 - 4.
Answer:
Sample is biased
Step-by-step explanation:
In her experiment, Gloria assumes that the reading habits of the students in her school district are exactly the same to that of students in all state schools. This assumption is unlikely to be true and, therefore, this statistic is misleading because the sample used is biased.
From her data, all Gloria can do is report the percentage of students that read more than one book per month in her school district.
