Answer:
3x^2−13x+4
Step-by-step explanation:
(x−4)(3x−1)
=(x+−4)(3x+−1)
=(x)(3x)+(x)(−1)+(−4)(3x)+(−4)(−1)
=3x^2−x−12x+4
=3x^2−13x+4
Option A. 3x² - 13x + 4 is the answer.
A conference room is in the shape of a rectangle. Its floor has a length of (x - 4) and width of (3x - 1) meters.
The expression that represents the area of the room is (x - 4)(3x -1) meter²
We further simplify this expression representing the area of the conference room.
(x - 4)(3x -1) = x(3x -1) - 4(3x -1) [Distributive law]
= 3x² - x - 12x + 4
= 3x² - 13x + 4
Option A. 3x² - 13x + 4 is the simplified form of the given expression.
to be honest I agree that would be 6s
