Final answer:
To find the equivalent expression to 3(−4.2y − 13.6), each term inside the parentheses is multiplied by 3, resulting in −12.6y − 40.8. The correct answer is Option D.
Step-by-step explanation:
The student is looking to find an expression equivalent to 3(−4.2y − 13.6). To do this, we distribute the 3 across the terms inside the parentheses.
Multiply 3 by −4.2y to get −12.6y.
Multiply 3 by −13.6 to get −40.8.
Combining these products gives us the equivalent expression −12.6y − 40.8. Thus, the correct answer is Option D.
