7 x 2 = 14
3 x 1 = 3
14+3 = 17
answer 17 unit^2
        
             
        
        
        
11x11 is 121 a way to remember it is there is one number on the left one number on the right and they add up to be 2 numbers total
        
                    
             
        
        
        
I think the answer is
B. ) 4/5 of the balls in the bag are red.
        
             
        
        
        
First graph it
#1
Maximum height is the y coordinate of vertex
Max height
#2
Time is the x coordinate of vertex
#3

x intercepts are the solutions
Take it positive
#4
put in function
- y=-16(1)+64+80=-16+144=128ft
