1. The number beneath the number that is to the left of the number that is 37 is 8.
2. The three numbers with a sum of 100 and a product of 225 are 15, 9, and 76.
3. The row with a sum of 20 less than the sum of the two diagonals is the second row.
Question 1:
The number beneath the number that is to the left of the number that is 37 is 8.
This can be seen in the image, where 8 is located directly below 37 in the grid.
Question 2:
The three numbers with a sum of 100 and a product of 225 are 15, 9, and 76.
To find these numbers, we can start by factoring 225, which is 15^2.
This means that one of the numbers must be 15.
We can then divide 225 by 15 to get 15, which is another one of the numbers.
The third number must be 100 - (15 + 15) = 70.
Here is a step-by-step solution:
Factor 225: 225 = 15^2
Choose one of the factors as one of the numbers: 15
Divide 225 by the chosen number to find the second number: 225 / 15 = 15
Subtract the two numbers from 100 to find the third number: 100 - (15 + 15) = 70
Therefore, the three numbers are 15, 9, and 76.
Question 3:
The row with a sum of 20 less than the sum of the two diagonals is the second row.
To find this, we can first calculate the sum of the two diagonals: 25 + 9 + 34 + 37 + 58 + 66 = 229.
Then, we can calculate the sum of each row and column:
Row 1: 25 + 13 + 37 = 75
Row 2: 42 + 8 + 9 = 59
Row 3: 66 + 58 + 34 = 158
Column 1: 25 + 42 + 66 = 133
Column 2: 13 + 8 + 58 = 79
Column 3: 37 + 9 + 34 = 80
We can see that the second row has a sum of 20 less than the sum of the two diagonals: 229 - 59 = 170.
Therefore, the answer to Question 3 is the second row.
