Answer: 4

Step-by-step explanation:

We can plug in the x and y values into the expression.

Then, we get 2*(-4) + 12.

Because of the order of operations, we calculate 2* -4 first to get -8 +12.

Lastly, we add -8 and 12 to get 4.

What is the area of a regular hexagon if a side is 30
sergij07 [2.7K]
<h3>Answer:</h3>

1350\sqrt{3} square units (approximately 2338.26859)

<h3>Step-by-step explanation:</h3>

The formula for finding the area of a regular hexagon when you know its side length is A=\frac{3\sqrt{3}*s^2}{2}, where A is the area and s is the side length.

  1. Substitute in the side length. A=\frac{3\sqrt{3}*30^2}{2}
  2. Simplify the exponent. A=\frac{3\sqrt{3}*900}{2}
  3. Multiply. A=\frac{2700\sqrt{3}}{2}
  4. Divide. A=1350\sqrt{3}

1350\sqrt{3} is as simple as the solution can get without estimating, but you can estimate with a calculator to find that it is approximately 2338.26859.

Recall that the range is the distance between the smallest and largest values. Or put another way, it is equal to the difference of the min and max

Range = Max - Min

So if we're told the range is 3, then this means the smallest and largest data values are 3 units away from each other

Answer: Choice B
