What side lengths should be used to model the rectangle? a rectangle with an area of x2 - 4x - 12 square units is represented by the model (x + 2) and (x-6) (x+6) and (x - 2) (x + 2) and (x - 10) (x + 10) and (x - 2) -x - +x - - - - - - - - - - - - +x

For this case we have that by definition, the area of a rectangle is given by:

Where:

a, b: They are the sides of the rectangle

We have as data that the area of the rectangle is given by:

IF we factor the expression, we must find two numbers that when multiplied give as a result "-12" and when summed give as result "-4". These numbers are: -6 and +2:

Thus, the sides of the rectangle are given by:

Option A
