15 times what equals 45

Answer: -30

Step-by-step explanation:

6(-5)

The negative sign will still stay.

Hence, 6x -5

= -30

Feel free to ask any questions. I'd be glad to explain.

Answer:

There will be 8 columns

Step-by-step explanation:

So first you get 48 and divide it by 6 then you get 8 as your answer

Final answer:

If polygon ABCD with vertices A (1, 2), B (1,4), C(2,6), and D (5, 4) is dilated by a factor 3, the coordinates of the dilated polygon are A' (3, 6), B' (3, 12), C' (6, 18), and D' (15, 12).

Explanation:

When a polygon is dilated by a scale factor, all the coordinates of its vertices are multiplied by that scale factor. In this case, the scale factor is 3. Thus, we should multiply the x and y coordinates of each vertex by 3.

Let's calculate:

1. Vertex A (1, 2) dilated by scale factor 3 becomes A' (1*3, 2*3) => A' (3, 6)
2. Vertex B (1,4) becomes B' (1*3, 4*3) => B' (3, 12)
3. Vertex C (2,6) becomes C' (2*3, 6*3) => C' (6, 18)
4. Vertex D (5, 4) becomes D' (5*3, 4*3) => D' (15, 12)

So, the coordinates of the dilated polygon ABCD are A' (3, 6), B' (3, 12), C' (6, 18), and D' (15, 12).
