Answer:
7/12
Step-by-step explanation:
5/6 = 10/12
1/4 = 3/12
10/12 - 3/12 = 7/12
Answer:
Step-by-step explanation:
Robert Boyle was one of the most prolific figures in the scientific revolution and the leading scientist of his day. He discovered the Boyle's law, which shows that the volume and pressure of a gas are proportionally related.
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.
Correlation coefficient is always between -1 and +1. So it cannot be +2.3
