1/2=3/6
3/6+1/6=4/6 goodluck
X/7-3=6
X/7=6+3
X/7=9
7x9=63
63/7-3=6
9-3=6
I would say choice “C”
The given statement is false because it isn't an empty set!
<u>Step-by-step explanation:</u>
We have following sets of inequalities:

From
we get ,

Therefore solution set is x=2.
Now, for
we get ,

Therefore solution set is x>2.
For
we get ,

Therefore solution set is x<2.
Now, the union of x=2, x<2 & x>2 is -∞<x<∞. i.e. all possible values of x. And so above statement is false because it isn't an empty set!
B
Because 2 sqrt5 is = to sqrt 20.
4^2=16, 6^2=36
Coefficients are ,5,20 variables are w,m and constant is 50
