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.
I think you have the right answer already
The formula for the law of sines is:
sin(A)/a = sin(B)/b = sin(C)/c
Big letters denote angle measures while smaller letters denote side lengths.
Answer:
88
Step-by-step explanation:
Looks close to a right angle so 88 degrees most likely.
Answer:
Answer down below.
Step-by-step explanation:
First of all, you need to start with the second section, which is 2 times -1
Doing that, will result with -2, since a positive times a negative = negative, and 2 times 1 = 2
Then, do -2 minus 4, and that gives you -6
Hope this helps!
