How I can answer this question, NO LINKS, if you answer correctly I'll give u brainliest!

Simplifying

0.25k + 1.5 + -1k + -3.5 = 0

Reorder the terms: 1.5 + -3.5 + 0.25k + -1k = 0

Combine like terms: 1.5 + -3.5 = -2 -2 + 0.25k + -1k = 0

Combine like terms: 0.25k + -1k = -0.75k -2 + -0.75k = 0

Solving -2 + -0.75k = 0

Move all terms containing k to the left, all other terms to the right.

Add '2' to each side of the equation. -2 + 2 + -0.75k = 0 + 2

Combine like terms: -2 + 2 = 0 0 + -0.75k = 0 + 2 -0.75k = 0 + 2

answer = -0.75k-2

-0.75k-2.0

Step-by-step explanation:

0.25k+1.5-k-3.5

0.25k-(1)k+1.5-3.5

0.25k-1.0k-2.0

-0.75k-2.0

- 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

3x + 4y -25 =0 represents the amount of change sianna should recieve
