Step-by-step explanation:

General Formulas and Concepts:

Algebra I

Reading a Cartesian Plane

Step-by-step explanation:

We can disregard the length of the line from the Library and the House, as Davina does not use that path at all.

We know that 1 unit on the grid represents 1 km. We define the lengths of the route from the graph:

Davina's House to School = 4 units = 4 km

School to Library = 6 units = 6 km

The entire trip Davina takes from House to Library would be 4 km + 6 km = 10 km total.

We also know that Davina takes the same route back from the Library to House. It would be the same exact route and length. Therefore:

2(10 km) = 20 km total

Answer 2

a. Formal operational.

Step-by-step explanation:

The formal operational stage is the fourth and final stage of cognitive development according to Jean Piaget. This stage approximately starts at the age of twelve and last into adulthood. At this stage, the children tend to think more advanced and abstract. Children would able to understand theoretical concepts and their practical application in real life. They can use their creativity to form new concepts.
