A right rectangular pyramid when sliced vertically, the shape of the cross-section is known as Triangle.
<h3>What is A triangle?</h3>
This is known to be a kind of shape that is said to be in a closed form and it is also known to be a 2-dimensional shape that has 3 sides, 3 angles, and also 3 vertices.
Note that when the when the right rectangular pyramid is sliced vertically (down) by a plane passing through the of the pyramid, the new shape of the cross-section is a triangle.

Answer:
A. a reflection over the x-axis and then a reflection over the y-axis
B. a reflection over the y-axis and then a reflection over the x-axis
Step-by-step explanation:
When you apply reflection over the x-axis, the transformation will change the y coordinate into -y. A similar thing happens when you do reflection over the y-axis, x coordinate will be -x. Both things will not influence each other so the sequence is not important. The resulting transformation will be equal to reflection to the point of origin.
There are a lot of numbers that fall into that category...
Lets call your number x, then 400 < x < 312
That means x can be any number in between 400 and 312. But, x cannot be 400 or 312
x can be a total of 87 numbers which are listed here:
