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.

Answer: B

Step-by-step explanation:

(x^2+4x+2) (2x^2+3x-4)

= x^2 (2x^2+3x-4) + 4x (2x^2+3x-4) +

2 (2x^2+3x-4)

= 2x^4 + 3x3 - 4x^2 + 8x^3 + 12x^2 - 16x + 4x^2 + 6x - 8

= 2x^4 + 11x^3 + 12x^2 - 10x - 8

There were 13426 eligible votes for a certain election.One day,8206 people cast their votes.What was the percent of voter turn o
coldgirl [10]
<h2>Greetings!</h2><h3>A way to do this is to divide the actual amount by the predicted amount:</h3>

8206 ÷ 13,426 = 0.6112

<h3>To change this back into a percentage simply multiply by 100:</h3>

0.6112 x 100 = 61.1

<h3>So the percent of voter turn out was 61.1%</h3><h2>Hope this helps!</h2>
