Answer:
2(2x + 5)(2x - 5)
Step-by-step explanation:
2(2x + 5)(2x - 5)
= (4x + 10)(2x - 5)
= 8x² - 20x + 20x - 50
= 8x² - 50
 
        
             
        
        
        
Answer:
588 in³
Step-by-step explanation:
Break it up in three parts.
Left part: 7*8*3 = 168
Mid part: 6*6*7 = 252
Right part: 7*8*3 = 168
Sum: 168+252+168 = 588
 
        
                    
             
        
        
        
The answer is the second option, <ACE = <ECA.
This is because C is in the middle of both, so it's referring to the same angle. The other options are all comparing different angles, that aren't congruent, so they're incorrect.
