The area of a triangle whose height is 1 more than 6 times its base is 13 square feet.  if the base of the triangle is  x  feet, which equation models this situation?
a. 
6x2  +  x  − 12 = 0
b. 
6x2  +  x  − 13 = 0
c. 
6x2  +  x  − 26 = 0
d. 
36x2  + 6x  − 26 = 0

There is a line with slope 1/a going through the point (a, a²). find the equation of the line perpendicular to this line at this point. (don’t let this problem intimidate you! solve the problem as you would if i’d given you specific values. just use variables instead.)
