In the case 4 is the cross section a square.
Here, we have,
To determine which case represents a cross section of a cube that is a square, we need to look for a cross section where all sides are of equal length and all angles are right angles, which are the defining characteristics of a square.
we know that,
When a plane intersects a cube, the resulting cross section can have various shapes, such as rectangles, triangles, or irregular polygons.
To determine if the cross section is a square, the conditions are:
If we can visually inspect the diagrams, carefully examine the sides and angles of the cross sections shown in each case.
in case 4, there is the presence of equal sides and right angles.
we can find in case 4 where all sides are equal and all angles are right angles, then that case 4 represents a square cross section of the cube.

Answer: Intersection 4
Step-by-step explanation: If you are talking about this question, then the answer is intersection 4.
In the problem, if we denote the number of lions as x, the number of tigers as x+2, and the number of bears as x+3, and considering that the total of all these animals is exactly 20, we can form and solve a simple algebraic equation. We will find that there are 5 lions, 7 tigers, and 8 bears.
This is a problem of simple algebra. According to the problem, let's represent the number of lions as x, the total number of tigers as x + 2 (since it's two more than the lions), and the number of bears as x + 3 (1 more than the number of tigers).
The problem states the total number of all these animals as 20, so we can set up the following equation: x + x + 2 + x + 3 = 20.
Solving this algebra equation gives you:
3x + 5 = 20
Subtracting 5 from both sides gives us:
3x = 15
Dividing both sides by 3 gives us:
x = 5
So, the number of lions is 5, the number of tigers is 7 (5 + 2), and the number of bears is 8 (7 + 1).

Answer:
[See Below]
Step-by-step explanation:
✦ First split the equation in little pieces and solve them:
✧ 4 - 16 = -12
✧ 4 + 4² = 20 (4² = 16)
✦ Now divide them:
✧ -12 ÷ 20 = -0.6
So I'm guessing you're trying to simplify 4²... so it'd be 16 because none of the choices are the simplified version of the problem.
