adding the two polynomials will give you the answer a
When the balloon is on the ground, it is at point 0. It starts to go up at 5 f/m for a time of 4 minutes. So we will multiply 5 by 4 to get 20. At this point, the balloon is 20 feet off the ground. However, we now know that the balloon descends at 2 f/m at a time of 7 minutes. So we must multiply 2 by 7 to get 14. So we know it was at 20, and then it went down by 14.
20 - 14 = 6 feet
This means that the balloon is now 6 feet above the ground.
I hope I've helped! :)
= [3x3^-2x(-2)^6/2x3^-1x(-2)^5]^2 = 1
Answer:
36
Step-by-step explanation:

The last one (D) is not right. The corresponding lines share the same ratio but they need not be equal.
D <<<< answer.
