Phil gets a commission of 25% on all sales. he sold $1500.00 worth of goods. what was the amount of his paychec
mihalych1998 [28]
375. 25% of 1500 is 375. You multiply 1500 by .25 to get your answer. When finding percentages of totals, you move the decimal place two places to the right of the percentage and multiply it by the total you need to find the percentage of.

1) Not a polynomial. Because x² is in the denominator.

2) Yes, it is a polynomial.

Standard form: 5x² + 2x - 99

3) Not a polynomial.

\sqrt{8x^{3}} = (8x^{3})^{\frac{1}{2}} = 8^{\frac{1}{2}}x^{\frac{3}{2}} .

Power of x is a fraction. so , it is not a polynomial.

4) Power of x is (-2). Power of x should not be a negative integer. SO, it is not a polynomial.

5) Yes:

Standard form: -3x⁴ + 12x² + 7x
