Answer:

You cant add them so it is probably a trick question.

Step-by-step explanation:

We would need to determine “u”

The area of a 2D form is the amount of space within its perimeter. The total surface area of the square base pyramid is 297mm².

What is an area?

The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm2, m2, and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.

The total surface area of the square pyramid is the sum of the area of the triangles and the area of the base. Therefore, the total surface area is equal to,

Total surface area = Area of square base + 4(Area of a triangular face)

                               = (9mm)² + 4(0.5×9×12)mm²

                               = 81mm² + 216mm²

                               = 297mm²

Hence, the total surface area of the square base pyramid is 297mm².

The Middle school team scored three field goals worth three points each and two touchdowns worth six points each, Including extra points. Write a numerical Expression to find the team's score.

Answers

Answer:
21
Step by step explanation:
So, what we know is that we have 3 field goals, each worth 3 points, and 2 touchdowns, each worth 6 points. So we can do: 3 * 3 + 2 * 6. To break this down we first must do 3 * 3. This gets us an answer of 9, we then must do 2 * 6. Which gives us an answer of 12. Now that we have multiplied the 2, we may add, 9 + 12 = 21. Meaning our answer is 21. I hope this helped you out!

the vertices of △ABC are ​A(-5,4),B(-2,4),and C(-4,2). If ABC is reflected across the​ y-axis to produce the image △ABC​, find the coordinates of the vertex C


the coordinates of C are...

Answers

Answer:

(4, 2)

Step-by-step explanation:

Because ABC is reflected across the y-axis, this means that the y coordinate will remain the same, and the x coordinate is the negative of its original (because it is being flipped)

If the vertices of △ABC are ​A(-5,4),B(-2,4),and C(-4,2). If ABC is reflected across the​ y-axis to produce the image △ABC​, then coordinates of the vertex C is (4,2)

What is coordinate system?

a coordinate system is a system that uses one or more numbers, or coordinates, to uniquely determine the position of the points or other.

Given that,

Vertices of △ABC are ​A(-5,4),B(-2,4),and C(-4,2).

If ABC is reflected across the​ y-axis to produce the image △ABC.

We need to find the image of △ABC.

We need to find coordinates of vertex C.

As ABC is reflected across the y-axis, this means that the y coordinate will remain the same,

As the triangle is flipped the sign of x coordinate is the negative of its original.

Hence (4,2) is the coordinates of the vertex C.

Why does the Moon appear to be the same size as the Sun during a solar eclipse?
Group of answer choices

Gravity pulls the moon closer to the Earth during a solar eclipse due to the planetary alignment so it ends up looking larger than normal.

While the moon is much smaller than the sun, the moon is also much closer to Earth so it appears larger.

The Moon Illusion occurs when the moon is in certain positions in the sky, which plays a trick on our brain to make it appear larger than it really is.
