Determine which factors below can be the dimensions of a rectangle with an area of .
Alenkinab [10]

Answer:

B


Step-by-step explanation:


Area of a rectangle is length * width.

The question asks which of the following (length * width) will give the expression for area...


<em>We multiply each, and whichever is equal to the expression for area given, is the answer. We use the distributive property to expand.</em>

<em>Distributive property is  a(b+c)=ab+ac</em>


A.

(3x-7)(4x+9)\\=12x^2+27x-28x-63\\=12x^2-x-63

This is not the answer.


B.

(3x+7)(4x-9)\\=12x^2-27x+28x-63\\=12x^2+x-63


We don't need to do more because B is equal to the expression of area given.

B is the correct answer.
