A contractor bought 10.84 of sheet metal. She has used 23 ft so far and has 5170 worth of sheet metal remaining. The equation 108x-234= 170 represents how much sheet metal is remaining and the cost of the remaining amount. How much does sheet metal cost per square foot?
how much sheet metal is remaining and the cost of the remaining amount. How much does sheet metal cost per square foot

i had no idea

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.
