For each exercise, write a single expression$/$statement that refers to the specified variables. $($You

should test them by assigning actual values to those variables and then writing expressions that

refer to those variables until you get the correct answer. See the next section for an example. For

problems $3$ and greater you will need to choose appropriate values for the variables$).$ Most

problems are adapted from Perkovic's Introduction to Computing Using Python $(2$nd Edition$).$

Suppose that we have assigned $s1=\text{'}-\text{'}$ and $s2=\text{'}+\text{'}.$ Write an expression that refers to

the variables $s1$ and $s2$ and that evaluates to

Suppose that we have assigned $s1={?}^{\text{'}}-\text{'}$ and $s2={?}^{\text{'}}+.$ Write an expression that refers to

the variables $s1$ and $s2$ and that evaluates to

The variable side contains the length of a side of a cube. Write an expression that returns

the volume of the cube.

The variables length and width refer the dimensions of a rectangle. Write an expression

that results in a value of True if and only if the rectangle has area $100$ or more.

The variables days holds an integer value. Write an expression that compute the number of

complete weeks spanned by that number of days. For example if days $=27,$ then thelctivate Windo

expression would evaluate to the integer $3($not quite $4$ because that would require $28$ days$).$ng to acti
