Kylie goes to a store an buys an item that costs x x dollars. She has a coupon for 30% off, and then a 4% tax is added to the discounted price. Write an expression in terms of x x that represents the total amount that Kylie paid at the register.

1) XX x .30 = D

2) XX - D = XX

3) XX x 1.04 = XX

Example: $20

$20 x .30 = 6

$20 - $6 = $14

$14 x 1.04 = $14.56

Dont know the answer to bad for u hahahahahah

Step-by-step explanation: get better

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.
