Hello,
Answer B: false
the parallelogram is a rectangle
6= 4(z+9)/y+2
6y +12 =4(z+9)
6y=4(z+9) -12
y=(4(z+9)-12)/6
y=2z+18-6/3
y=2z+12 /3
Explanation:
If you plug 4 in for x into the equation, the equation becomes this:

When you simplify the equation;

Simplify it further,

That is correct. 6 = 6
Hope that answered the question.
