Answer:
466.2 ft²
Step-by-step explanation:
10x24=240
1/2 12²=226.194671
12²=226.194671
240+226.194671=466.194671
 
        
             
        
        
        
Answer: 3
Step-by-step explanation: The additive inverse of -3 is 3.
 
        
             
        
        
        
x^3=54 (Subtract 3 from both sides)
x = 3rd power cube root of 54 (Cube root both sides)
27 = 3^3 (3x3x3) therefore  
                                                x = (3) (3rd power cube root of 2)
