How do you write the expression for the area given the length (x+6) and width (x-3)?

Answer 1

For a rectangle the expression would be: #A = (x + 6) * (x - 3)# or #A = x^2 - 3x - 18#

If we assume that this is a rectangle, the area formula is:

#A = l * w# where #A# is the area of the rectangle, #l# is the length of the rectangle and #w# is the width of the rectangle.
In this problem we are provided the length and width which we can substitute for the #l# and #w# is the formula to give:
#A = (x + 6) * (x - 3)#

By cross-multiplying, we can extend this to a quadratic equation, which yields:

#A = x^2 + 6x - 3x - 18#
#A = x^2 - 3x - 18#

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
