Answer:
x = -3 and x = -3/2
Step-by-step explanation:
After writing down the polynomial, split it; put a line between 3x^2 and -18x. Look and 2x^3 + 3x^2 and -18x - 27 separately and factor them both:
p(x) = 2x^3 + 3x^2 <u>- 18x -27</u>
p(x) = x^2(2x+3) <u>-9(2x+3)</u>
Now notice how x^2 and -9 have the same factor (2x+3). That means x^2 and -9 can go together:
p(x) = (x^2 - 9)(2x+3)
Factor it once more because there's a difference of squares:
p(x) = (x+3)(x-3)(2x+3)
Now just plug in whatever makes the each bracket equal 0:
x = -3, x = 3, and x = -3/2
Those are your zeros.
Answer:
9.42857142857 inches = 1 inch
Step-by-step explanation:
12 inches in a foot
12 × 5.5 = 66
66 / 7 = 9.42857142857
Answer:
Step-by-step explanation:
r = 9.3 ft
h = y ft
Volume = 3000 ft
πr²h = 3000
3.14 * 9.3 *9.3 * y = 3000
y = 11.05 ft
