A. 2

Step-by-step explanation:

The quadratic formula is:

An equation of the form    is only quadratic when , therefore it is linear.

Also, by definition, a quadratic equation is an equation where the highest exponent is a square.

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
