The answer is 12 including both sides and angles.
When you cut a square piece of paper from one point to the opposite point it should make two triangles.
Thus each triangle has 3 sides and 3 angles so two triangles has 6 angles and 6 sides
So 12, sides and angles added together.

Step-by-step explanation:
 
        
             
        
        
        
The US equivalent of "liters to meters" would be something like
"quarts to yards", which is equally meaningless.
Liters and meters don't even measure the same thing.  Liters describe
volume, whereas meters describe length or distance.    They don't convert
to each other .
If volume units could be converted to length units, then you (or somebody 
with a slightly better grasp of his math) would be able to figure out how many 
inches of gas he put into his car last week, and the cost of a foot of milk.  
        
             
        
        
        
Answer:
8 + 1.50x + 0.75y = 19.25
Step-by-step explanation:
Let the number of additional inch = x
Let the number of toppings = y
From the question, 
A 10-inch cheese pizza costs $8. 
Each additional inch costs $1.50
Each additional topping costs $0.75. 
The equation that represents Josh's pizza is when his total cost amounts to $19.25 is:
$8 + $1.50 × x + $0.75y = $19.25
8 + 1.50x + 0.75y = 19.25
