Question
Solve the quadratic equations and determine the relation
between x and y: Equation 1: x² - 40x + 300 = 0 Equation 2: y² - 30y + 216 = 0Solution
From Equation 1: x² - 40x + 300 = 0 Factorizing: (x - 10)(x - 30) = 0 So, x = 10 or x = 30. From Equation 2: y² - 30y + 216 = 0 Factorizing: (y - 12)(y - 18) = 0 So, y = 12 or y = 18. Comparing x and y: x = 10, y = 12, x < y x = 10, y = 18, x < y x = 30, y = 12, x > y x = 30, y = 18, x > y Correct option: E) x = y or no relation
? = ((64.13 - 34.97) + 16.89) x 1.98
(1096.01 ÷ 7.99) - (120.98 ÷ 10.88 X 6.99) = ? ÷ 4.99
(74.93% of 640.11 + 3/4 of 359.79)² - (1/3 of 80.87 × 2)² = ?
(12.13) 2 - 19.93 + 39.78 - 42.93 = ?
16.99% of 399.99 ÷ 17.17 = ? ÷ 15.15
(20.98 ÷ 2.91) + (15.12 – 5.96) = ?Â
{44.78% of (11.67 × 54.78)} ÷ 2.65 = ? + 19.25
63.95 – 21.12 – 24.89 + 6.04 = 3.98 × ? + 3.88
