The Pythagorean theorem tells you the square of the hypotenuse is equal to the sum of the squares of the sides.
  BC² = AB² + AC²
  BC² = 4² +4² = 32
  BC = √32 = 4√2
  BC = 4*1.41 = 5.64
The length of segment BC is 5.64 m.
        
             
        
        
        
Hello! The question simplified is 4x + 14. This is because when you have a negative symbol in front of the numbers you need to distribute, you change the numbers inside into the opposites, and then multiply by -1. When you do this, you get 3 + 4x + 5 + 6. When you combine like terms, you get 4x + 14. The answer is B: 4x + 14.
        
                    
             
        
        
        
2x^3+x^2-15x factored completely would be: <em>x(x+3)(2x-5).</em> Not sure which answer choice but I hope that I was some help.
