The length of a rectangle is 6 inches more than it’s width. if the perimeter of the rectangle is 24 inches, find the dimensions. create let statement and write equation.

The dimensions of the rectangle are;

Width = 3 inches

Length = 9 inches

Step-by-step explanation:

Given;

We want to determine the dimensions of the rectangle;

Forming an equation, we get;

2 ( x + x + 6) = 24

4x + 12 = 24

With the equation we can solve for x

4x = 24 - 12

4x = 12

  x = 3

and (x + 6) = 9

Therefore;

Width = 3 inches

Length = 9 inches

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.
