HELPP ASAP! PLEASE ! The silver carving of width 4 cm is made around outside of the frame of a photo of 24 cm X 28 cm.
a) Find the area of the silver part .
b) If the cost of 1 cm² silver carving is Rs. 550 what will be the total cost required for the whole carving? find it.​

24 units

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.

according to egenuity the answer is
