Question 2: D
Question 1: C
Question 3: B
Question 4: C
Answer:
12a+8b-28
Step-by-step explanation:
Distribute
4(3a+2b-7)
4×3a=12a
4×2b=8b
4×-7=-28
So
12a+8b-28
2(4-16) - (-30)
= 2(-12) -(-30)
= 24 - (-30) ....Error right here....a negative multiplies a positive = negative (= -24 + 30)
= 24 + 30
= 54
Correct:
2(4-16) - (-30)
= 2(-12) -(-30)
= -24 - (-30)
= -24 + 30
= 6
