Which expression shows a way to factor 15 + 18? Choices: (A)6(2 + 3) (B)5(3 + 4) (C)2(7 + 9) (D)3(5 + 6)

Identify GCF of 15 and 18: Step 1: Identify the Greatest Common Factor (GCF) of 15 and 18. To find the GCF, list the factors of each number: Factors of 15: 1, 3, 5, 15 Factors of 18: 1, 2, 3, 6, 9, 18 The GCF of 15 and 18 is 3. Express using GCF: Step 2: Express 15 + 18 using the GCF. Using the GCF, 3, we can write 15 + 18 as 3(5 + 6). Match with choices: Step 3: Match the factored expression with the given choices. The expression 3(5 + 6) matches choice (D).
