Answer:
(a) x = -0.418 , -3.581
(B) c = 6.855, -1.855
Step-by-step explanation:
(A) We have given equation 

On comparing with standard quadratic equation 
a = 2, b = 8 and c = 3
So roots of the equation will be 
(b) 

a = 1, b = -5 and c= -14
So
It is a 100 degrees vertical angles are congruent
Given A = {a, e, i, o, u} and B = {a, l, g, e, b, r}, find A ∪ B.

Ahh..this is sets topics - A U B = all the elements found in A and B. But do note, do not repeat the elements if it is the same. And if the question were to ask : n(AUB) = total number of elements found in A and B.
Answer:
C
Step-by-step explanation:
-4+(-5)=-9
-4=-9+5
-4=-4......correct
7 over 21 . because you add 7 plus 8 plus 6 and get 21 then have 7 white shirts
