b=135 because opposite angles of a parallelogram are congruent is correct because the angles are opposite each other in the parallelogram and congruent means equal so angle b must equal 135.
Hope this helps!!
OK.....
Your answer would be -3x^5y^6

Answer:
(x-6)^2 =40
Step-by-step explanation:
The correct answer is (x-6)^2 =40
why??
Expand (x-6)^2
x^2 -12x+36 =40
Transpos 40 to the left side
So,
x^2 -12x+36 -40
Which is
x^2 -12x -4=0
The last two answers would be correct. This is because pi is an irrational number, 22/7 is a rational number, and 3.14 is a rational number.
