Arectangle with an area of x2 – 4x – 12 square units is represented by the model. what side lengths should be used to model the rectangle? (x + 2) and (x – 6) (x + 6) and (x – 2) (x + 2) and (x – 10) (x + 10) and (x – 2)

 The correct option is (A)

Step-by-step explanation:  The area of a rectangle is given as follows:

We are to find the side lengths that should be used to model the rectangle.

The AREA of a rectangle is the PRODUCT of its length and width.

So, in order to find the dimensions, we need to factorize the expression for the area.

The factorization is as follows:

Therefore, the dimensions of the rectangle are

Option (A) is correct.

these sign is used to tell weather the number is greater or less than the number   <   or >     but this sign means its equal =

step-by-step explanation:

statement #3: proof- ang is congruent to ang ecd : angles are congruent.  

step-by-step explanation:

1: the missing angles in statement #3  

a.) acb  

reason- the reason why the answer is acb is because angle ecd and angle acb are both the same size *that's what the word congruent means this is really simple.  

2: the missing word in reason #3  

c.) vertical  

reason- the reason why the answer is vertical is because the angles in that diagram on figure 2 is slanted, which is vertical, and the e and a both lay on vertical lines. along with the other's, but e and a are the 2 main points you want to focus on. and c is kind of like your starting point, because c is for both angles, not just one.  

i hope that was and understanding.
