Determine whether QR & ST are parallel, perpendicular, or neither. Q(-8, 7), R(-7, 2), S(-8, 13), T (-11, -2)

The two points are parallel

Step-by-step explanation:

To answer this problem would need a plot on a graph

kindly find attached a rough plot for your reference

from the rough plot, we can see that the points

Q(-1,4), R(-1, -9),

and  S(11,-2),T(11,6)​ are parallel

- 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

answer for #1 is c

answer for #2 is d
