What is the greatest common factor of 42 and 55?

The GCF of 42 and 55 is 1.

Step-by-step explanation:

sorry it took me a while to write in my book

42 AND 55 ARE A PAIR OF CO-PRIME NUMBERS

CO PRIME:a pair of numbers which have the only common factor as 1 is called as co prime

answer: procent 54 wynosi 33,33%

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.
