Answer:
3/8 of the pitcher of lemonade remains.
Step-by-step explanation:
They tell us that at first they had 7/8 of a pitcher full of lemonade, and they ask us to know what fraction is left if they have taken 1/2 of the pitcher of lemonade for a while, which means that it would be a subtraction between what had at the beginning and what they have taken, would be:
7/8 - 1/2 = (14 - 8) / 8 * 2 = 6/16 = 3/8
Which means that 3/8 of the pitcher of lemonade remains.
Use this formula: 180(n-2), 'n' being the number of sides of the polygon. But you are right about the pattern of the sum of the interior angles.

Complete the square
factor out linear coefient
f(x)=7(x^2+6x)
take 1/2 of linear coefient and square it and add negative and positive to inside
6/2=3, 3^2=9
f(x)=7(x^2+6x+9-9)
complete squre
f(x)=7((x+3)^2-9)
expand
f(x)=7(x+3)^2-63 is veretx form
vertex is (-3,-63)
