On the rectangle A, we have the following expressions represented with the squares:
For rectangle B we have:
Comparing the expressions, we have the following:
[tex]\begin{gathered} 2x+1>2x \\ -3x-1<-x+1 \end{gathered}[/tex]
the first inequality is true since a number plus 1 is always going to be greater than the number alone (in this case, 2x). In the second inequality, -3 times a number is alwas less than -1 times that number.
