Answer:
C(x) = 
Step-by-step explanation:
Data provided in the question:
Area of the field = 3600 square feet
Fencing charges = $3.50 per foot
Let the side along the river be 'x' feet and the other side of the 'B'
now,
Area of rectangle = Bx = 3600 square feet
or
B = 
 feet
and total length to be fenced = x + 2B
therefore, 
Total cost of fencing = Fencing charges × total length to be fenced
or
Total cost of fencing = $3.50 × ( x + 2B )
substituting the value of B from (1)
Total cost of fencing, C(x) = 
or
C(x) = 
 
        
             
        
        
        
B and C are both correct

Answer:
6in 
it would be 6inches 2sides or 12 an one be 6
 
        
             
        
        
        
x = the length of one piece
y = the length of the other piece
the total length is 100 cm this means 
x + y = 100
one piece is 16 inches longer than the other
first we need to convert inches to cm: 
1 in = 2.54 cm
16 in = 2.54*16 = 40.64
now we can write
x = y + 40.64
by solving the system of equations
x + y = 100
x = y + 40.64
we find
x = 70.32 cm
y = 29.68 cm
the lengths of the two pieces are 70.32 cm and 29.68 cm.
 
        
             
        
        
        
Answer:
35
Step-by-step explanation:
All angles of a triangle add up to 180 degrees, so you can add the other two angles, then subtract by 180.
