Sharita does special typing jobs for scientists. she charges 13$ for the first 3 pages and 3$ for each additional page of scientific typing. sonia , a biologist , paid 103 to have a research paper typed ?

33 pages because you subtract 13 from 103 which is 90 then divide that by 3 and that gives you 30 pages then you add the other 3 pages that costed $13.

- 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

y -5 = (-1/4)(x + 8)
