Write an expression that represents the area of the rectangle. Remember A = LW
a)6x2−3x
b)9x2−3x
c)6x-1
d)12x - 2

Answer:
b) 9x² - 3x
Step-by-step explanation:
Area of a rectangle = Length × Width
Area for the rectangle = 3x - 1 × 3x
Area = [tex](3x-1)(3x)[/tex]
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
