Question

Activity 3 of 3 Create an expression that represents the area of the rectangular room. Then, write the expression as a polynomial in standard form. Show you work/steps. 3x + 6 4x - 1 4x-1 Door

Answer 1

We have a rectangular room with sides of (3x+6) and (4x-1).

We can calculate the area multypling both sides:

$\begin{gathered} (3x+6)(4x-1) \\ 3x\cdot4x+6\cdot4x+3x\cdot(-1)+6\cdot(-1) \\ 12x^2+24x-3x-6 \\ 12x^2+21x-6 \end{gathered}$

The expression for the area of the rectangular room is:

$12x^2+21x-6$
