Question

A conference room is in the shape of a rectangle. Its floor has a length of (x − 4) meters and a width of (3x − 1) meters. The expression below represents the area of the floor of the room in square meters.

(x − 4)(3x − 1)

Which of the following simplified expressions represents the area of the floor of the conference room in square meters?

Answer 1

multiply the factors by each other to get the polynomial, cancel out like terms

Answer 2

What do you mean @jdoe0001

Answer 3

well, just multiply the 2 binomials there \(\bf (x − 4) \times (3x − 1)\)

Answer 4

3x^2-x-12x+4? @jdoe0001

Answer 5

yes

Answer 6

hmmm one sec

\(\bf 3x^2 -12x-x+4 \implies 3x^2-13x+4\)

Answer 7

ohh, I forgot to simplify

Answer 8
