Hope this helps :D
<u>Answer:</u>
Quadratic expression
<u>Step-by-step explanation:</u>
We are given a rectangle with the dimensions and .
We know that:
<em>Area of a rectangle = length x width</em>
Therefore, we will put in the given values of the length and width of the rectangle to find it area.
Area of rectangle =
=
=
So we can say that the area of this rectangle is represented by a quadratic expression.
Answer: (0,0) is a proportional relationship. The graph should at zero. It means that in a y=mx+b form. Either B should be zero or just not there which would change into a proportional relationship y=kx
