(2x-4)(x+5)  expand with indicated multiplication...

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

2x^2+6x-20  (it's the top one :P)

The area of a rectangle is represented by the equation [tex]2x^{2} +6x-20[/tex].

Given: Rectangle

One side (Length) = 2x - 4

Other side (Breath) = x + 5

The area of a rectangle is given by

[tex]Area = Length\times Breath[/tex]

[tex]Area = (2x-4)\times (x+5)\\Area = 2x^{2} +10x-4x-20\\Area =2x^{2} +6x-20[/tex]

Therefore, The area of a rectangle is represented by the equation [tex]2x^{2} +6x-20[/tex].
