A car rental company rents cars based on a fixed daily charge and $0.45/km. The cost for one day and driving it for 200 km is $107.45. How much would it cost to use the car for one day and travel 250 km?

(w – 2.5)(w + 2.5)

(–4v – 9)(–4v + 9)

step-by-step explanation:

you can't solve x because it is 2 linear equation and you only have one equation

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.

180-142=38 for the acute angle next to the entry

90+38=128

180-128=52

a=52
