−8 ≤ 2/5 (k−2)
Can you please provide the step by step to get to the answer? Thanks!

k ≥ -18

Step-by-step explanation:

-8 ≥ 2/5(k-2)

-8 ≥ 2/5k - 4/5

(-8 ≥ 2/5k - 4/5) 5

-40 ≥ 2k - 4

+4           +4

-36 ≥ 2k

-36 divided by 2

2 divided by 2

-18 ≥ k

flip the greater than or equal to sign to the k.

k ≥ -18

- 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
