Answer 1

Answer:

Given that ;

Length of the Rectangle ( l ) = 4x² - x + 2

Width of the Rectangle ( w ) = 5x - 3

Perimeter of the Rectangle ( P ) = ?

Formula :

Perimeter of the Rectangle ( P ) = 2 ( l + w )

P = 2 ( 4x² - x + 2 ) + 2 ( 5x - 3 )

P = 8x² - 2x + 4 + 10x - 6

P = 8x² + 8x - 2

Hence ;

Perimeter of the Rectangle

In Quadratic Equation :

= 8x² + 8x - 2

Common Factor :

2 ( 4x² + 2x - 1 )
