Step-by-step explanation:

In the picture attached, the Truth Table for the operator “OR”  is shown. With it we can compute the next table:

p   q ∧ r   p ∨ (q ∧ r)

T      T          T

T      F          T

F      T          T  

F      F          F

We want that p would be false and p ∨ (q ∧ r) would be true, which corresponds to the third row of the previous table.

The only row from the table of the question that satisfies this criterion is row E.

- 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

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9
