Y = x^2 + 10x - 171
y = (x - 9)(x + 19)
x - 9= 0 x + 19 = 0
x = 9 x = -19
Answer B covers all requirements... the factored form is
<span>y= (x + 19)(x - 9) </span>
<span>and the zeros are -19 and 9</span>
        
                    
             
        
        
        
1 is a whole and 1/2 is just a fraction

Answer:
Step-by-step explanation:
1x+3x+4x= 128
8x=128
x=128/8
x=16
therefore,
room 1 = 1x
            = 1*16=16
room 2 = 3x
             =3*16=48
room 3 = 4x
             =4*16=64
