Answer:
1. 3x = 9
2. 2x + 4 > 8
3. -7x + 4 < -2x² + 10
4. x³ - 21 < x²-2
5. x² + 2x - 10 < x² + x + 5
Step-by-step explanation:
1. 3(3) = 9
9 = 9
2. 2x + 4 > 8
2(3) + 4 > 8
6 + 4 > 8
10 > 8
3. -7x + 4 < -2x² + 10
Calculate : -17 < -8
4. x³ - 21 < x² - 2
(3)³- 21 < (3)²-2
27 - 21 < 9 - 2
6 < 7
5. x² + 2x - 10 < x² + 3+ 5
(3)³ + 2(3) - 10 < (3)² + 3 + 5
9 + 6 - 10 < 9 + 3 + 5
5 < 17
