Avery has 12 marbles total. 2 x 6 = 12
for 
when a=1, then the value of c that will make the quadratic a perfect square (allows you to complete the square) is 
given x^2+x
b=1
so 
answer is C
Answer:
4
Step-by-step explanation:
The radius of the circle times 2 to make it the diameter, because the diameter of the circle is the same as the side length.
I'm going to assume we're finding the slope
-6 + 2 = -4
5 - 4 = 1
-4/1 = -4
-4 is your answer for the slope
I'm not sure what your question was, I just guessed.
