Answer:
Step-by-step explanation:
Given equation to us is ,
So , a equation is said to be a quadratic equation if the highest degree of the variable is 2 . On simplifying the Equation ,
Taking x as LCM ,
Transposing x to RHS .
Putting all terms in LHS
Since here the highest degree of the variable is 3 not 2 . So its a cubic equation and not a quadratic equation .

Answer:
perimeter = x + x + 2x + 2x
Step-by-step explanation:
- Perimeter of a rectangle = 2W + 2L
(where W is the width and L is the length)
Let x = one of the width side lengths:
⇒ 6x = 2x + 2L
⇒ 6x - 2x = 2L
⇒ 4x = 2L
⇒ 4x ÷ 2 = L
⇒ 2x = L
Therefore, perimeter = x + x + 2x + 2x
