this seems easy, but idk.

Directrix (directrix):

The area of a rectangle is found by multiplying its length by its width. So, here we go again with the multiplication of binomials. Think of this as a continuation of the type problem you just did.

Directrix (directrix):

Area = (2x - 4) * (x + 5) Multiply those and then add the like terms.

OpenStudy (anonymous):

2x(x) + 2x(5) + -4(x) -4(5) @Directrix

OpenStudy (anonymous):

Correct so far?

Directrix (directrix):

Yes, it is correct so far.

Directrix (directrix):

Multiply and show the individual products but do not add just yet. Okay?

OpenStudy (anonymous):

oops 2x+ 10x + -4x - 20

Directrix (directrix):

2x(x) is not equal to 2x. Try again.

OpenStudy (anonymous):

2^2?

OpenStudy (anonymous):

or no.
