Which of these true conditional statements has a false converse?

a) if 2x = 4, then x = 2.

b) if a figure is a triangle, then the figure has three sides.

c) if a figure is a square, then the figure has four sides.

Not sure if I'm right but i think the answer is C.

If a figure has four sides, its not always a square. It could be a trapezoid, or another four sided shape. The other converses for A and B are true.

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3
