Brian as 8 cards.
The fraction that show how many are baseball cards is 5/8, because 5 cards from the total amount are baseball cards. Good luck !
Steps:
(n-2) * 180 = sum of interior angles
(3-2) * 180 = 180
Bottom Triangle
25 + 51 + x = 180
x = 104
Top Triangle
104 + 34 + x = 180
x = 42
Answer:
42
Answer:
it should be B.
Step-by-step explanation:
Answer:
Step-by-step explanation:
You need to use vertex form of a quadratic to solve this.
Consider the vertex to be 
Another way of representing a quadratic is in "vertex form":

Now all you have to do is solve for a. You know that the vertex is
and you have know the point of
. Now, all you have to do is plug in these values and solve for a.

Now you know the equation is
, but you need it in quadratic form. All you have to do is solve is distribute the 6:

You get:
a = 6
b = 0
c = 2
