Timed i will pick brainliest aviva is comparing her age to her sisters’ ages. kanti is 3 years younger. aviva’s older sister, lakshmi is twice as old as kanti. which expression correctly completes the table? ' sister’s ages sister aviva x kanti x-3 lakshmi ? a) 2x - 3 b) 2(x-3) c) 2x d) (x - 3) + 2

let

x> Aviva’s age

y>Kanti’s age

z> Lakshmi’s age

we know that

y=x-3> equation 1

z=2*y> equation 2

substitute equation 1 in equation 2

z=2*(x-3)

so

Aviva’s age> x

Kanti’s age> x-3

Lakshmi’s age> 2*(x-3)

therefore

the answer is the option

b) 2(x-3)

40% off the regular price is the correct answer.

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.
