Answer:
x = -1/2 + (i/2)√11 and x = -1/2 - (i/2)√11
Step-by-step explanation:
This polynomial is a quadratic. Its coefficients are a = 1, b = 1 and c = 3.
Thus, the discriminant b^2-4ac is 1^2 - 4(1)(3), or 1 - 12, or -11.
Because the discriminant is negative, the roots are complex.
The roots are:
-1 ±√(-11) -1 ±i√11
x = --------------- = ----------------, so x = -1/2 + (i/2)√11 and x = -1/2 - (i/2)√11

G. Division Property of Inequality
Answer:
3/7 and 2/7.
Step-by-step explanation:
P(e) = No of favourable outcomes/ Total no of possible outcomes.
total outcomes=3+1+1+2=7.
(1) p(D) = 3/7.
(2)p(A)=2/7
A is 180 degrees, B is 180 degrees, C is definition of complementary angle, D is 180-angle 2, and E is angle 3.
16. 5(7)+13 /8
35+13/8
48 /8
6 is the answer for 16
17. 45+40= 85
85 is the answer
