The dimensions of a rectangle are x+4 and 3x-1. Write an expression to represent the area of the rectangle.

Step-by-step explanation:

Step 1:  Multiply them together to get the area

3x² + 11x - 4

Step-by-step explanation:

Area = length × width

= (x+4)(3x-1)

= 3x² + 12x - x - 4

= 3x² + 11x - 4
