Answer:
n(B) = 1350
Step-by-step explanation:
Using Venn sets, we have that:

Three values are given in the exercise.
The other is n(B), which we have to find. So




So
n(B) = 1350
If s = 1/4 unit and A = 80s^2
A = 80 (1/4)^2
A = 80 (1/16)
A = 5
Answer
5 square units
5/8, 1/9....these are in simplified form because they cant be reduced
12/15 simplifies to 4/5
4/8 simplifies to 1/2
9/18 simplifies to 1/2
Science = 14 x 6 = 84
so equation
y = 12x + 84
your answer is correct
