User: Select the correct product. (2x + 9)(x + 1) 2x2+ 11x+ 9 3x2+ 11x+ 9 2x2- 7x+ 9 2x2+ 11x+ 10

User: (2x + 9)(x + 1)

Weegy: If h(x) = 5 for the function h(x) = 2x + 1, then x equals 2. h(2) = 2(2) + 1 = 5. The answer is 2.

User: 36m5n5 ÷ (12m3)

(2x + 9)(x + 1)
= 2x^2 + 2x + 9x + 9
= 2x^2 + 11x + 9

7 - 3[(n^3 + 8n) ÷ (-n) + 9n^2]
= 7 - 3(-n^2 - 8 + 9n^2)
= 7 - 3(8n^2 - 8)
= 7 - 24n^2 + 24
= -24n^2 + 31
