Step-by-step explanation:
<h2>
The required "option D) 54 + 42 = 6(9 + 7)" is correct.</h2>
Step-by-step explanation:
We have,
The sum of 42 and 54
= 42 + 54
∴ 42 and 54
42 = 2 × 3 × 7 and
54 = 2 × 3 × 3 × 3
The greatest common factor of 42 and 54
= 2 × 3
= 6
∴ 42 + 54
= 6(7 + 9)
= 6(9 + 7)
Thus, the required "option D) 54 + 42 = 6(9 + 7)" is correct.
