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:
![\begin{gathered} 2x+1>2x \\ -3x-1<-x+1 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/1t4xqxvks9guypvo6cyavwuug50xdrvw92.png)
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.
