THE ANSWER IS B Show the results of your calculations for the reflection.
Answer:

Step-by-step explanation:
We need to find the distance between the points (5, 2) and (1, 9). In order to do this, we will use something called the distance formula. The distance formula is written as follows:

Now we need to plug in our points which we have given in the form (x, y):

Next, perform the operation of subtraction inside the parentheses to simplify:

The exponent is the next step in the order of operations, so square 4 and -7:

Finally, add 16 to 49:

The square root of 65 cannot be simplified further, but an approximation can be made.
≈ 8.062257748
Answer:
16 units squared
Step-by-step explanation:
First, calculate the distance between (0, 0) and (0, 4). The distance is in y, so there are 4 units in-between.
Next, calculate the distance between (0, 0) and (4, 0). This time, the distance is in x, but it is still four.
We know the dimensions of the shape are 4x4 so we just multiply.
4*4=16
The space diagonal will have length ...
... d = √(1² +4² +2²) = √(1 +16 +4) = √21
_____
This can be found using the Pythagorean theorem. A drawing can help. Find the length of any face diagonal, then use that length as the leg of a right triangle whose hypotenuse is the space diagonal and whose other leg is the edge length not used in the first calculation.
