Question

2. Write an expression for the perimeter of a rectangle with a length of

(3x² + x + 2) and a width of (-x² – 5x + 1).

Answer 1

2 × [(3x² + x + 2) + (-x² – 5x + 1)] =

Explanation:

Write an expression for the perimeter of a rectangle with a length of

(3x² + x + 2) and a width of (-x² – 5x + 1).

P = 2 × (L + W)

2 × [(3x² + x + 2) + (-x² – 5x + 1)] =

if you want the result:

4x²−8x+6
