Answer:
224
Step-by-step explanation:
Number of trains in the roller coaster = 2
Number cars in each train = 7
Total number of cars = Number of trains 
Number of cars in each train = 
= 14
Number of people in each car = 16
Total number of people in 14 cars = Number of people in one car Number of cars = 16 14 = 224
i.e.
Total number of people in the roller coaster in one run = 224
Number of runs made by each train in one hour = 10
Therefore, Total number of people that can ride the roller coaster in one hour can be found by multiplying the number of runs with total number of people in the roller coaster in one run.
224 10 = <em>2240</em>
Although the terms might seem intimidating, this is a simple substitution problem.
X + Y = _______
Substitute the values of X and Y in terms of w
(7w^2 + 4w - 6) + (w^2 - 11w + 13) = ______
Now all you need to do is combine like terms (terms that have the same variables raised to the same power)
8w^2 - 7w + 7
Final Answer: 8w^2 - 7w + 7
