Which of the following represents the area of a rectangle whose length is x-7 and whose width x+12 ? @waterineyes

OpenStudy (anonymous):

Where are the followings? :P Am I blind?? :)

OpenStudy (one098):

Oh haha sorry. They are: x^2+5x-84 x^2-84 x^2-5x-84 x^2-84x+5

OpenStudy (anonymous):

\[Area_{rect} = Width \times Length\]

OpenStudy (anonymous):

So, you got: \[Area = (x+12)(x-7)\]

OpenStudy (one098):

Yes

OpenStudy (anonymous):

Can you multiply it?

OpenStudy (anonymous):

In Stupid Town, may be it is said to do FOIL, right?
