Question
Simplify the expression: (9x² - 25) / (3x + 5)
Solution
Factor the numerator: 9x² - 25 = (3x - 5)(3x + 5) Now the expression becomes: (3x - 5)(3x + 5) / (3x + 5) The simplified expression is 3x - 5. Correct Answer: a)
What approximate value will replace the question mark (?) in the following?
? = 1...
386.99 + 397.99 + ? - 232.02 = 35.02 × 31.99Â
11.11% of 1800.89 + 34.89 X 10.99 - 500.50 = ?
- What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.)
(48/16)2 × 50/50 ÷ 50/800 = ? Â
What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.)...
? = 25.08 + 14.99 × 25.07
Find the approximate value of Question mark(?). No need to find the exact value.
(519.79 ÷ 10.03) × (47.98 ÷ 6) + √(63.94) × 4.04 = ?
...80.08% of 1250.25 + 64.02% of 1200 = 24.02 × 36.025 + ?% of 2259.98
28.95% of 924.78 + 1955% of 38.99 = ?
