Answer:

(x² + 4x + 2)(2x² + 3x - 4) equals 2x⁴ + 11x³ + 12x² - 10x - 8

Step-by-step explanation:

<em>(x² + 4x + 2)(2x² + 3x - 4)</em>

Multiply each term in the first parentheses into the expression in the second parentheses.

<em>2x⁴ + 3x³ - 4x² + 8x³ + 12x² - 16x + 4x² + 6x - 8</em>

Combine like terms.

<em>2x⁴ + 11x³ + 12x² - 10x - 8</em>

So, your answer would be letter choice B.

  • The 8th grade students that have pets = 175 - 68 = 107
  • Total students that have pets = 102 + 107 = 209

the second one 9v+36

Step-by-step explanation:

because with the way it set up it wants you to multiply 9 by everything inside of the parenthesis so 9 times v is 9v and 9 times 4 is 36 thus 9v+36 and you also take the addition symbol from inside the parenthesis.
