The diameter is
inches as shown in the readings of the scale.


If you mean this one then:
Yes it is a perfect square, since you get a whole number as the original points
And the answer is C
Hey there!
To solve for the solutions of your inequality, divide both sides of your inequality by -3 in order to isolate the value of x:
-3x≥36
÷-3 ÷-3
x≤12
**Note: in inequalities, if you ever divide or multiply a number that is negative, you must flip the inequality sign. In this case, because you have divided -3 from both sides, you must flip the inequality sign from ≥ to ≤.
Therefore, your solutions to your inequality would be x≤12.
Hope this helps, and have a nice day! :)
