I. 6 y² + 11 y – 7= 0 6 y² + 14 y - 3 y– 7= 0 2 y(3 y + 7) – 1(3 y + 7) = 0 (2 y – 1)(3 y + 7) = 0 y = 1/2,- 7/3 II. 21 x² + 5 x – 6 = 0 21 x² + 14 x - 9 x – 6 = 0 7 x(3 x + 2) – 3(3 x + 2) = 0 (7 x – 3)(3 x + 2) = 0 x = 3/7, -2/3 Hence, relationship cannot be established between x and y
(65% of 120) = 25% of ? - 22
15% of ? = 30% of 320 + 17 ×√676 – 63.5 × 8
115% of 40 + 3 × 4 = ? × 11 – 8
The value of 5³ × 5⁴ × 5² = ?
136% of 560 - 2/7 of 630 + 45% of 420 =?
16 of 25 - 12 of 15 = ? of 5 of 11
(0.1 × 0.2 × 0.3) + (0.3 × 0.4 × 0.5) =?
Find the HCF of 15x2 + 8x – 12, 3x² + x – 2, 3x² - 2x, 9x² - 12x + 4
The value of 0.0486 ÷ 0.002 =
