Multiply -12 to each of the terms (make sure to carry the negative!)
-36a - 24b + 12 will be your final answer :)
Answer: Answer is D and Yes
Step-by-step explanation:
7 mph; 1/2 hour multiplied by 2 equals an hour so you just multiply 3 1/2 by 2 and you get 7.
D. -2/3 because when you do (y2-y1)/(x2-x1) you get -4/6 which simplifies to -2/3
The answers would be 12 and -16
