Answer: -30 ==> A
Step-by-step explanation:
a = 3 and b = −4
12(a • b + a2) + 6=
12(a • b + a^2) + 6=
12(3 • (-4) + 3^2) + 6=
12(-12 + 9) + 6=
12(-3)+6=
-36+6=
-(36-6)=-30 ==> A
Answer:
a) -30
Step-by-step explanation:
Given that,
→ a = 3
→ b = -4
Let's solve the problem,
→ 12(a × b + a²) + 6
→ 12(3 × -4 + (3)²) + 6
→ 12(-12 + 9) + 6
→ 12 × -3 + 6
→ -36 + 6 = -30
Hence, the answer is -30.
