Write an expression that represents the area of the rectangle. Remember A = LW

Iteru [2.4K]

Answer:

b) 9x² - 3x

Step-by-step explanation:

Area of a rectangle = Length × Width

Area for the rectangle = 3x - 1 × 3x

Area = $(3x-1)(3x)$

Step 1. Multiply by combining like terms

3x · 3x = 9x²

Step 2. Multiply -1 by 3x

-1 · 3x = -3x

Step 3. Combine 9x² and -3x

9x² - 3x
