Steps for solving:
Start by putting your x's together on the left side of the inequality by subtracting 2x from both sides to give you 6x - 6 > 12.
Next, put your numbers together on the right by
adding 6 to both sides and we have 6x > 18.
Divide both sides by 6 and <em>x > 3</em>.
I have also graphed x > 3 for you on a number line.
Just start with an open dot at 3 and we use an open dot because x > 3 but it is not equal to 3 and then we draw an arrow to the right on our number line to represent all numbers greater than 3.
Finally, you can write your answer
in set notation which is {x : x > 3}.
All this means is that if we take any number greater than 3 and plug it back in for <em>x</em> in our original problem, we will get a true statement.
In this problem, 5 is the only value that would make this inequality true because it's greater than 3.

Answer:
the area is 50.24 .
Step-by-step explanation:
The formula to find area of a circle is A=π. A is area, and r is for radius. Since we have the diameter here, we just need to divide by 2 to find the radius. 8÷2=4, so there, the radius is 4. Now we need to square 4, and do 4x4, which equals 16. Now to multiply 16 by π, or 3.14. 16 x 3.14 = 50.24. The final answer is 50.24

When taking square roots, you can't take square roots of negative roots of negative numbers. So, what will work for the domain of u(x) is what makes u(x) zero or more. We can make an inequality for that.
u(x) ≥ 0.
9x + 27 ≥ 0 by squaring both sides
9x ≥ -27
x ≥ -3
So the domain of the function is when x ≥ -3 is true.
