The width of a rectangle is 2 feet less than it’s length. Find it’s width of the perimeter is 68 feet

The length is 18 and the width is 16

Step-by-step explanation:

The sides of the rectangle are

Width: x-2

Length: x

To find the perimeter get all 4 sides and add them all up

x-2+x-2+x+x=68

4x-4=68

x=18

The length is 18 and the width is 16

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.
