Find the perimeter of the polygon.

W: 4ft
L: 7ft

How do I slove it?

If your looking to solve the perimeter, your looking for the total distance around the box. Add  up the length of each of the 4 sides. The formula would be: (w x 2)+(Lx2)

(4x2)+(7x2)=

8+14=

22

perimeter is "22"

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.

step by step explanation: when u removing the parentheses and combined them that would be : x+3y-x-y=2y
