Arrange the following words in the order in which they

If x^2 - 7x + k = 0 has roots that are equal, what is the value of k?

I. 6x² – 7x - 20 = 0

II. 3y² - y - 14 = 0

I. 5x² + 17x + 6 = 0                                           

II. 2y² + 11y + 12 = 0

Solve for x: |2x − 5| + |x + 1| ≤ 10.

I: x² + 31x + 228 = 0

II: y² + 3y – 108 = 0

I. 88x² - 13 x – 56 = 0

II. 15 y² + 41 y + 28 = 0

I. 96x² + 52x - 63 = 0

II. 77y² + 155y + 72 = 0

Equation 1: x² - 45x + 500 = 0

Equation 2: y² - 60y + 600 = 0

Solve the quadratic equations and determine the relation between x and y:

Equation 1: 2x² - 8x + 6 = 0

Equation 2: y² - 7y + 10 = 0

I. x² – 10x + 21 = 0

II. y² + 11y + 28 = 0
