Answer:
ans:- 14
Step-by-step explanation:
let length = x
so, width= 2x -1
perimeter= 2(l +b)
82 = 2(x+ 2x-1)
41 = 3x - 1
3x = 42
x = 14
The easiest way for me is to use the integer rules
yes this is solved by the distributive property of multiplication.



therefore

The vertex of the function is (0,4)
