The equator is the circle around Earth dividing it into the northern and southern hemispheres. (The center of the earth is also the center of the equator.) What is the length of the equator?

Do the mean numbers of letters in the first and last names for everyone in your class give you enough information to make conclusions about students’ names in your entire school? For example, if we want to study the heights of people on different sports teams, the population would be all the people on the teams.

Another line, below the cotton line, is slanting up and to the right, through the origin, is labeled nylon. For example, the points \((2,12)\) and \((3,12)\) tell us that at store B you can get more pounds of blueberries for the same price. The points \((3,12)\) and \((3,18)\) tell us that at store A you have to pay more for the same quantity of blueberries.

It can be a single number, a variable, or a number and a variable that are multiplied together.

The radius of the smallest circle is one unit, and the radius of each successive circle is one unit more than the previous one. Since the circles on the grid are the same distance apart, segment \(PA'\) has twice the length of segment \(PA\), and the same holds for the other points.

To factor an expression, we use the distributive property to rewrite a sum as a product. For example, we can factor the expression \(20x+35\) to get the equivalent expression \(5(4x+7)\). In each row, decide whether the expression in column A is equivalent to the expression in column B.
