Question

Write a simplified polynomial expression in standard form to represent the area of the rectangle below x+5 and 2x-4

Answer 1

It would be 2x^2 + 6x-20

Answer 2

Answer:

$2x^2+6x-20$

Step-by-step explanation:

The sides of the rectangle are x+5 and 2x-4

To find the polynomial that represents the area of the rectangle , multiply the sides of the rectangle

$(x+5)(2x-4)$

Apply FOIL method to multiply it

$(x+5)(2x-4)$

$2x^2-4x+10x-20$

Combine like terms

$2x^2+6x-20$

Area of the rectangle is $2x^2+6x-20$
