Answer:
The model is shown in the attached picture. The solution is 10.
Step-by-step explanation:
There are two way of showing a model for 2×5
- The tape diagram has 2 equal-sized parts of 5
- The tape diagram has 5 equal-sized parts of 2
Both models give the same solution:
- 5+5=10
- 2+2+2+2+2=10
In the attached picture we can show two types of diagram.

Since two people take both courses, we can subtract two from 7, 8, and 21, giving us 5, 6, and 19. 
Add 5 and 6 together to get 11. Since eleven students are in those two groups, we can answer this. The answer will be 11/19.
        
             
        
        
        
Answer:
C:  g(x) = 3x^2
Step-by-step explanation:
Note that (1, 1) is on the graph of f(x) and that (1, 3) is on the graph of g(x).  This indicates that the coefficient of x^2 is 3 for g(x).
