Area of a trapezoid = ((a+b)/2) * h
a = x + x
b = z + z
h = y
A = ((4 + 12)/2) * 6
A = ((16)/2) *6
A = 8 * 6
A = 48
answer is B

Answer:
the answer is A y_ intercept =2 and slope =-3
D
It can give some balls more chance to be picked, making it unfair
Answer:
C would be equal to (f - 13)/(10 - d)
Step-by-step explanation:
In order to find this, you must manipulate the equation so that the left side has every term with a c in it. Then you can isolate it by dividing and find what it is equal to.
10c - f = -13 + cd -----> Add f to both sides
10c = f - 13 + cd -----> Subtract cd from both sides
10c - cd = f - 13 ------> Pull out c
c(10 - d) = f - 13 -----> Divide by (10 - d)
c = (f - 13)/(10 - d)
