Use A' for A complement, etc. and n = intersection ∩.
n(A' n B')
=n(A u B)' by the de Morgan's law
=nU-n(nA+nB-n(AnB)) n(A u B) = nA + nB - n(AnB) and nX'=nU-nX
=400-(135+80-60)
=400-155
=245
something noteworthy is that in the equation the variable with the positive sign is the "y", meaning is a vertical hyperbola that has a vertical traverse axis.

Answer:
1.26885245902 or rounded to $1.27 per pound.
Step-by-step explanation:
you can just divide 3.87/3.05 to see how much each pound costed. if you needed to round to the nearest cent, you would round up to 1.27.... or if not, keep it at 1.26885245902.

Answer:
Option D)12
Step-by-step explanation:
Given is a parallelogram ABCD with side lengths given as
AD=12 and DC=18
We are to calculate the side length of BC
Recall the properties of a parallelogram.
Opposite sides are parallel and equal
Hence we have BC = AD
So measure of BC = 12
Answer is
Option D)12
