If the scale is 2 inches = 4 feet, what are the actual side lengths of the garden?

a 2 feet, 3 feet, 2 feet, and 4 feet
b 4 feet, 6 feet, 4 feet, and 8 feet
c 8 feet, 12 feet, 8 feet, and 16 feet
d 16 feet, 24 feet, 16 feet, and 32 feet

c

Step-by-step explanation:

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.
