In order to have an infinite number of solutions, it should be that the two equations are identical. Therefore, I believe the correct answer is option c. The value of b should be 6. Hope this answers the question.
        
             
        
        
        
The cheese pizzas is $6.00 each. The four-topping pizzas are $10.00 each. 
The expression would be $6c + $10f because the c and f are variables and the variables stand for the amount of pizzas they ordered.
        
             
        
        
        
So before we can find the perimeter, we need to find the hypotenuse. Since this is a right triangle, we can use the pythagorean theorem. The equation for that is  , in which a and b are the legs of the triangle and c is the hypotenuse.
 , in which a and b are the legs of the triangle and c is the hypotenuse.
With this info, we can form our equation: 
Firstly, solve the exponents: 
Next, combine everything on the left side: 
Next, square root both sides, and your hypotenuse will be 15 = c.
Now that we have all the triangle side lengths, just add everything up: 
In short, the perimeter is 36 inches.
