Answer: Its B
Explanation:
The expression 6(a-3) can be simplified by applying the distributive property of multiplication over addition, which gives 6a - 18. Therefore, the expression is equivalent to 6a - 18. The answer is (b) –2. All other options do not simplify to the same expression as 6(a-3). For example, 18a is not equivalent to 6(a-3) and neither is 6(a)-6(3). Option (d) 1 simplifies to 6a - 18a + 18, which is not equivalent to the original expression. Similarly, 6(a)-3 simplifies to 6a - 3, which is also not equivalent.
