Answer:
$45
Step-by-step explanation:
Let the regular price be x
according to the question
the equation is
x×85/100=38.25
x×85/100=38.25
x=38.25×100/85
x=38.25×20/17
x=45
The answer is (B).
If we substitute r = 6 inches into the volume of a sphere formula we get this:

π6³
Since 6³ = 216, we multiply this by 1.3333 to get 288. If we multiply this by pi we get 288π, or (B).
Y=-4a+24
This is the answer hope that helps
Answer:
akk
Step-by-step explanation:
(x² + 3x - 1)(2x² - 2x + 1)
x²(2x² - 2x + 1) + 3x(2x² -2x + 1) -1(2x² - 2x + 1)
2x^4 - 2x³ + x² + 6x³ - 6x² + 3x - 2x² + 2x - 1
2x^4 - 2x³ + 6x³ + x² - 6x² - 2x² + 3x + 2x - 1
2x^4 + 4x³ - 7x² + 5x - 1
<span>(D)The result 2x4 + 4x3 − 7x2 + 5x − 1 is a polynomial.</span>
