A building in a city has a rectangular base. The length of the base measures 60 ft less than twice the width. The perimeter of this base is 870 ft. What are the dimensions of the base?

bn,mn,n.vn.

step-by-step explanation:

the answer is simply just 6n add the two together as they have an n

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.
