Examine the work shown. Explain the error and find the correct result.

2(4 – 16) – (–30)
2(–12) – (–30)
24 – (–30)
54

Answer 1

The product of the two numbers with different signs is negative so 2(-12)=-24 not 24. Then -24 -(-30)=-24 +30=6

Answer 2

Answer:

The error is in step 3. 24 -(-30). The correct answer would be -24-(-30)

Step-by-step explanation:

You are multiplying 2(-12) which would not give you a positive 24, but a negative 24 because a negative times a positive still gives you a negative. Once you have fixed that mistake, you continue on with the problem and your end product will be 6.

2(4−16)−(−30)

= (2)(−12)−(−30)

= −24−(−30)

= 6

I hope this helps you out!!
