6x+3y=6  and 8x+9y= -22  describes the outcomes of Clare and Noah.
Step-by-step explanation:
Let, 
x represents the number of points for a goal.
y represents the number of points for a penalty.
Therefore, 
6 goals = 6x
3 penalties = 3y
8 goals = 8x
9 penalties = 9y
According to given statment; 
6x+3y=6    Eqn 1
8x+9y= -22   Eqn 2 
6x+3y=6  and 8x+9y= -22  describes the outcomes of Clare and Noah.

Answer:
C=5+0.25m
Step-by-step explanation:
 
        
             
        
        
        
The expression representing the volume of the prism is given as:
Volume=[base area]*[height]
base area is the area of the pentagon;
The area of pentagon is given by:
Area of pentagon=a^2ntan(180/n)
a=apothem length
n=number of sides
Area=2.8^2*5tan(180/5)
Area=28.48=28.5 cm^2
Therefore the expression for the volume of the prism with height,h, will be:
volume=28.5h cm^3
