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.
H equals 30 because 3 times 6 is 18 so 5 times 6 is 30
Answer:
The radius is 4 feet
Step-by-step explanation:
<u>Area of a circle: A = π * r^2</u>
<u />
<u>Step 1: Solve for r</u>
16π / π = π * r^2 / π
sqrt(16) = sqrt(r^2)
<em>4 = r</em>
