The area of a rectangular room is given by the trinomial x + 3x - 28. what are the possible
dimensions of the rectangle? use factoring,
(x-7) and (x+4)
(x-7) and (x-4)
(x+7) and (x+4)
(x+7) and (x-4)

The possible  dimensions of the rectangle are (x+7) and (x -4).

Step-by-step explanation:

Here, the given expression  for area of the rectangle is:

Now, Area of the rectangle =  Length x Width

Hence, to find the dimensions, we need to factorize the given trinomial.

So,

⇒

⇒

So, the factors of the polynomial are (x+7) and (x -4)

Hence, the possible  dimensions of the rectangle are (x+7) and (x -4).

the answer should be a. snail
