Answer:
The approximate circumference is 62.8 mm
Step-by-step explanation:
Circumference is basically the perimeter of the circle
Circumference is given by

Here the diameter is 20 mm, so the radius will be half of diameter = 10 mm
Substituting the given values, in above equation, we get -
Circumference =
mm
The approximate circumference is 62.8 mm
If x, then not y, if not y, then z. Y is true. So: X is true, Z is True
<h3>How to Interpret Conditional Statements?</h3>
A conditional statement is a type of structure to express the relationship between two dependent variables. Its structure is as follows:
If P, then Q...
Now, from the question we are told that;
If x, then not y, if not y, then z.
Y is true. So:
Now, when looking at conditional statements in depth, and comparing to this question we can easily see that since Y is true, then it means that if X is true, then Z is also true.
Thus,
If x, then not y, if not y, then z.
Y is true. So: X is true, Z is True

2n+14=14+2n so this one as an infinite number of solutions. The second one 1-x=-x-6 so you add x on both sides which results in it having no solutions.
this is the equation x+9+8=7
