Need . will give brainliest. parallelogram fghi on the coordinate plane below represents the drawing of a horse trail through a local park: in order to build a scale model of the trail, the drawing is enlarged as parallelogram abcd on the coordinate plane. if two corners of the trail are at point a (−2, 7) and point d (−10, −1), what is another point that could represent point b? a. (14, 7) b. (10, 7) c. (12, 7) d. (8, 7)

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
