Step-by-step explanation:
Discriminant : k² - 4(12)(27) < 0
So k² - 1296 < 0, -36 < k < 36.
The surface area is 13630=1/2(4)(height)30=2(height)and from there we can solve. 30/2=15the height of the triangle is 15, which is also the slant heightto check our work, 1/2(4)(15)=304x15=601/2x60=30
-3. 91 is the sum of -2.16 and -1.75
