This is about problem solving patterns in 4th grade. The question asks What are the fewest nunber of buttons you need to make six rows in this pattern?Then to the right of the picture there is 6 buttons in one row and 5 buttons in the second row and 4 buttons in the third row. The next problem I need help with asks How many squares will be in the three center colums when the pattern is completed And then there is a blank space to write a number then 1 square in one row then 2v squares in the next row and 3 squares in the third row and then there is three blank spaces to write numbers in and after that there is 3 squares in one row then two squares in the next and one square in the third row.

what 2 + 4

To solve the first problem, let's analyze the given information. We are asked to determine the fewest number of buttons needed to make six rows in a pattern. The picture shows that there are 6 buttons in the first row, 5 buttons in the second row, and 4 buttons in the third row.

To find the pattern, we can observe that each row has one less button than the previous row. So, we can continue this pattern to determine the number of buttons in the fourth, fifth, and sixth row:

Fourth row: 4 - 1 = 3 buttons
Fifth row: 3 - 1 = 2 buttons
Sixth row: 2 - 1 = 1 button

Now, let's add up the number of buttons in each row to find the fewest number needed for six rows:
6 + 5 + 4 + 3 + 2 + 1 = 21 buttons

Therefore, the fewest number of buttons needed to make six rows in this pattern is 21 buttons.

Moving on to the second problem, we are asked to determine the number of squares in the three center columns when the pattern is completed. The provided information shows 1 square in the first row, 2 squares in the second row, and 3 squares in the third row.

To find the pattern for the number of squares in subsequent rows, it seems to be increasing by 1 each row:

Fourth row: 3 + 1 = 4 squares
Fifth row: 4 + 1 = 5 squares
Sixth row: 5 + 1 = 6 squares

Now, let's determine the number of squares in the three center columns when the pattern is completed:

First column: 1 + 2 + 3 + 4 + 5 + 6 = 21 squares
Second column: 1 + 2 + 3 + 4 + 5 + 6 = 21 squares
Third column: 1 + 2 + 3 + 4 + 5 + 6 = 21 squares

Therefore, there will be 21 squares in each of the three center columns when the pattern is completed.

Finally, you asked "what 2 + 4." Adding 2 and 4 together gives us the answer: 6.

2 + 4 is equal to 6.
