User: (–7x – 5x4 + 5) – (–7x4 – 5 – 9x) A. 2x4 + 2x + 8 B. –14x4 + 10x + 10 C. –14x4 – 10x + 10 D. 2x4 + 2x + 10

Weegy: Assuming the 4's are exponents: (?7x ? 5x^4 + 5) ? (?7x^4 ? 5 ? 9x) = D. 2x^4 + 2x + 10.

(2n^2 + 5n + 3)(4n – 5)
= 8n^3 - 10n^2 + 20n^2 - 25n + 12n - 15
= 8n^3 + 10n^2 - 13n - 15
