Write a simplified polynomial expression in standard form to represent the area of the rectangle below.

2x2 + 10x + 20
2x2 + 6x + 20
2x2 + 6x − 20
2x2 − 4x − 20

Write a simplified polynomial expression in standard form to represent the area of the rectangle below 2x2 10x 20 2x2 6x 20 2x2 6x 20 2x2 4x 20 class=

Respuesta :

Area = Length * Width
A = (2x - 4) * (x + 5)
A = 2x² +10x-4x - 20
A = 2x² + 6x - 20

In short, Your Answer would be Option C

Hope this helps!

Area= Length × Width
Area=(2x-4)(x+5)
Area=2x(x+5)-4(x+5)
Area=2x^2+10x-4x-20
Area=2x^2+6x-20

The answer is C. 2x^2+6x-20
