What is the trinomial that represents the area of a rectangular rug whose sides are (x+3) feet and (2x-1) feet?

Answer 1

Sadie Adams

#2x^2+5x-3#

Area of a rectangle is length #xx# breadth.

So in this case the area would be

#(x+3)*(2x-1)#

This we can multiply out to obtain

#2x^2+5x-3#.

The trinomial that represents the area of a rectangular rug with sides of length ( (x+3) ) feet and ( (2x-1) ) feet is obtained by multiplying the expressions representing the lengths of the sides:

[ \text{Area} = (x + 3)(2x - 1) ]

Expanding this expression gives:

[ \text{Area} = 2x^2 - x + 6x - 3 ]

[ \text{Area} = 2x^2 + 5x - 3 ]

So, the trinomial representing the area of the rectangular rug is ( 2x^2 + 5x - 3 ).

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.
