Question

the dimensions of the base of box 2 are $x$ by $4x - 1$.
$4x^2 - x$
$4x^2 - 1$
$4x - 4$
$5x - 1$

Explanation:

Step1: Identify base area formula

The area of a rectangular base is length × width.

Step2: Substitute given dimensions

Substitute length $x$ and width $4x-1$ into the formula.
$x \times (4x - 1)$

Step3: Expand the expression

Use the distributive property $a(b-c)=ab-ac$.
$x(4x) - x(1) = 4x^2 - x$

Answer:

A. $4x^2 - x$
