A and B are the roots of equation x² - 13x + k = 0. If A - B = 5, what is the value of k?

(i) x² – 3x – 40 = 0

(ii) y² + 11y + 30 = 0

I. 2x² – 10x – 48 = 0

II. y² – 16y – 297 = 0

I. 8/(21x) - 2/7 = 0

II. 16y² - 24y +9 = 0

I. 2y²+ 13y + 15 = 0

II. 2x²+ 11 x + 12 = 0

I. 6x² + 19x + 10 = 0

II. y² + 10y + 25 = 0

I. 2x² + 11x + 12 = 0

II. 2y² + 19y + 45 = 0

I. 63x² + 37 x – 40 = 0

II. 15 y² + 29 y + 12 = 0

I. 5x² - 28x + 39 = 0

II. 2y² - 13y + 20 = 0

I. 20y² - 13y + 2 = 0

II. 6x² - 25x + 14 = 0
