Simplify the expression:
(9xΒ² - 25) / (3x + 5)
β? Γ 4 - 374 + 127 + 300 = 117
Find the simplified value of the following expression:
14.25 Γ 32 β 11.4 Γ 15 + 8 β 712 Γ· 8 + 34.15 Γ 20 β 27 Γ 21 = ?
...- 55% of 220 β 15% of 40 = 20% of ?
(21 X 5) + ? = (480 - 120) Γ· 3
125 + 30% of 250 + β576 = ?
32 × 3 (54 – 15) + 186 ÷ 3 ÷ 2 – (21)² = ?
