Answer:
I'm pretty sure it is 18
Step-by-step explanation:
Since the shape is not a perfect square you can count how many blocks are shaded. However, the half shaded blocks, since they are half shaded you will need 2 half shaded blocks to make one block
 
        
             
        
        
        
Answer:
We know that the kite with the tail is 15 feet and 6 inches. While 6 inches is 0,50 foot, it's 15,5 feet. If the lenght of the kite is x, then:
15,5 = x + 1,5 + 2x
15,5 = 3x + 1,5     / - 1,5 (both sides)
14 = 3x             / : 3 (both sides)
x ≈ 4,66
The kite is approx .4,66 feet long. It means that the tail is about 15,5 - 4,66 = 10,84 feet long.
 
        
                    
             
        
        
        
The bold number (10) is the difference because it is calculated by subtracting two numbers.
        
             
        
        
        
Answer:
12
Step-by-step explanation:
3x^2
because the information provided states that x = -2, that is what we are going to replace x with. 
3(-2)^2
the next step is to evaluate the power because that is next in PEMDAS.
(-2)^2 = 4 
that leaves us with: 
3 * 4 = 12      ( the " * " represents the multiplication sign) 
hope this helps!
