Find the number of even numbers between 12 and 30.
ATQ, Since we have to find the even numbers between 12 and 30, 12 will not be included. So, even numbers between 12 and 30 are [14, 16, 18, 20, 22, 24, 26, 28]. So, there are 8 even numbers between 12 and 30.
I. 2x2 – 5x - 12 = 0
II. y2 – 11y + 30 = 0
I. 4x² - 15x + 9 = 0
II. 20y² - 23y + 6 = 0
I. (y – 5)2 – 9 = 0
II. x2 – 3x + 2 = 0
I. 2y² - 11 y + 15 = 0
II. 2x² + 3x – 14 = 0
I. 63x² + 146x + 80 = 0
II. 42y² + 109y + 70 = 0
I. 8x² - 74x + 165 = 0
II. 15y² - 38y + 24 = 0
I. 2y2– 19y + 35 = 0
II. 4x2– 16x + 15 = 0
I. x ² + 5 x + 6 = 0
II. y²+ 7 y + 12= 0
...I. p2+ 2p – 8 = 0 II. q2 – 5q + 6 = 0
I. y/16 = 4/y
II. x3= (2 ÷ 50) × (2500 ÷ 50) × 42× (192 ÷ 12)
