6. (6x4 + x3 – 9x + 13) = (x2 + 8)
what’s this answer

What is the standard form of -5x^2+2x^4-11+x^3+3x

Recall that the owner of a local health food store recently started a new ad campaign to attract more business and wants to know if average daily sales have increased. historically average daily sales were approximately $2,700. the upper bound of the 95% range of likely sample means for this one-sided test is approximately $2,843.44. if the owner took a random sample of forty-five days and found that daily average sales were now $2,984, what can she conclude at the 95% confidence level?

Ineed to know the ordered pairs for this equation i need the answer quick because it’s a timed test
