Two African tigers were weighed. One weighs 5x + 17
pounds and the two together
weigh 16x + 3 pounds. How
much does the other tiger
weigh alone?

Step-by-step explanation:

The weight of the other tiger is 11x - 14.

The total weight of the two tigers is 16x + 3.  Subtract the weight of one (5x + 17) from this total; the result is the weight of the other tiger:

  16x + 3

-  ( 5x + 17)

 11x - 14

The weight of the other tiger is 11x - 14.

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.
