Vertex formula = -b/2a
-18/1 = 18.
However, this is just the x value, the vertex is (x,y)
-18*2 + 18(18) - 72 = 576
A) (18,576)
576 dollars made with 18 members is the highest amount made in one day.
B) (12,0) (6,0)
Probability of any event = ( favourable outcomes ) /total number of outcomes
Probability of = 3/10 + 2/9 = 
Two shaped are merged so
One is square and the other is trapezoid so,
AREA OF SQUARE=4*4
=16
AREA OF TRAPEZOID=(2+4)x4/2
So,rhe answer will be
12+16=28
HOPE IT IS HELPFUL
