It's either a (the first one) or b (the second one), but if I had to choose I would choose b. If I'm wrong I'm so sorry I spent 10 minutes looking at this.

Answer:

Option A.

Step-by-step explanation:

ABCDE is a pentagon which has been transformed to form A'B'C'D'E'.

In this process two transformations have been done.

To check the transformations we select one point A and check it for all the transformations.

1) Point A has been shifted 7 units right on the x axis and 1 unit up on y- axis as per rule (x, y) → (x + 7, y + 1)

2) Now the translated image has been reflected across x - axis to form a new point A'.

Therefore, Option A. is the correct option.

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.
