Answer:
2.5 is less than 1,950.
Step-by-step explanation:
The decimal place is at the end of 1,950.
The decimal place is in the middle of the 2 and the 5.
Since 2.5 decimal place is closer, that means 2.5 has a lower value than 1,950.0.
You can subtract both values.
1,950 - 2.5 = 1,947.50, if it’s greater than 0, it means it has a lower value.
0 < 1,947.50.
Therefore, 2.5 < 1,950
a² - b² = (a - b)(a + b)
49x² - 9 = (7x)² - 3² = (7x - 3)(7x + 3)
