4. 3(3x - 1) a. 6x - 2 b. 9x - 3 c. 15x + 6 - 6x - 3

Question

  1. 3(3x - 1)

a. 6x - 2
b. 9x - 3
c. 15x + 6 - 6x - 3

Explanation:

Step1: Expand the expression

To expand \(3(3x - 1)\), we use the distributive property \(a(b + c)=ab+ac\). Here \(a = 3\), \(b=3x\), and \(c=- 1\). So we have \(3\times3x-3\times1\).

Step2: Calculate the products

\(3\times3x = 9x\) and \(3\times1=3\), so the expanded form is \(9x - 3\).

Answer:

b. \(9x - 3\)
