Answer: D.-6 and F.3
Step-by-step explanation:
The given rational number : 
To find : The value of x , where the rational expression becomes equal zero.
Let's check all the options :
A. 7
At x= 7 , 
B. -7
At x= 7 , 
C. 6
At x= 6 , 
D. -6
At x= -6 , 
E. -3
At x= -3 , 
F. 3
At x= 3 , 
Thus, at x= -6 and 3 , the rational expression equals to zero .
So , the correct options are : D.-6 and F.3
2x + 9 < 32
2x < 32 - 9
2x < 23
x < 23/2
x < 11.5 <==
Answer:
A
Step-by-step explanation:
The equation y =1, means that y is one for any value of x. Therefore you will get a straight horizontal line that goes through (-1,1) (0,1), (1,1), (2, 1) etc.. It will be parallel to the y-axis, but one unit up, as I have tried to illustrate below:

Answer: "
267.95 m³ " .
______________________________________________________Explanation:________________________________________________________V = (4/3) *
* r³ ;
Given: diameter, "d" = "8 m" ;
radius, "r" = 8 m / 2 = 4 m "
V = (4/3) *
* r³
V = (4/3) *
*(4m)³
V = (4/3) * (3.14) * 4³ * m³ ;
V = (4/3) * (3.14) * (4*4*4) * m³ ;
V = (4/3) * (3.14) * (64) * m³ ;
V = 267.9466666666666667 m³ ;
round to: "
267.95 m³ " .
