You would divide to have your answer!
Answer:
This would equal 3N+4
Step-by-step explanation:
The way this is simplified is by distributive property.
Step 1. Multiply 1/2 by all the numbers inside the parentheses.
Step 2. Do the math. So 1/2 of 6 would be 3. Now one have of 8 is 4.

We know that the balloon ascends at the same constant rate, that means that after the penny drop is:

this comes from the fact that the initial height is 500 ft and that for each second the balloon ascends 10 feet.
X = 35
use the formula a^2 + b^2 = c^2 in order to find the hypotenuse, which is x.
21^2 + 28^2 = c^2
441 + 784 = c^2
1225 = c^2
35 = c
x = 35
