Step-by-step explanation:

1. Let's find the equivalent of 12 1/2% as a fraction

12 1/2% = 12 + 0,5 = 12,5%

12,5 % = (0.125 * 100)/100

12.5% = 12.5/100

12.5% = 12.5 * 10/100 * 10 (Multiplying by 10 for getting an integer number in the numerator)

12.5% = 125/1,000

12.5% = (125/125)/(1,000/125) (Dividing by 125 in the numerator and in the denominator)

12.5% = 1/8

The correct answer is B. 1/8

step-by-step explanation:

- 2 + 10x³ - 21x² + 19x - 4

step-by-step explanation:

each term in the second factor is multiplied by each term in the first factor

x²(- 2x² + 4x - 1) - 3x(- 2x² + 4x - 1) + 4(- 2x² + 4x - 1) ← distribute

= - 2 + 4x³ - x² + 6x³ - 12x² + 3x -8x² + 16x - 4

collect like terms

= - 2 + 10x³ - 21x² + 19x - 4 ← in standard form
