The term 3x-4 in the equation is Option B. the length of the rectangle.

Step-by-step explanation:

Given that,

Perimeter of rectangle 2 (length+width) = 48 inches. Width of the rectangle = x inches. Length of rectangle = 4 inches shorter than 3 times the width ⇒ 3x-4

The equation can be formed as:

48 = 2 (x) + 2 (3x-4)

The term 3x-4 represent the length of the rectangle.
