Answer:
The correct answer is B. 2π
Step-by-step explanation:
A rational number is one that can be represented using a fraction and an irrational number cannot be represented using a fraction.
-√4 = -2, which is a rational number
2π is not a rational number (we cannot express pi as a fraction exactly even though there are some close approximations)
2.2121... is also a rational number because it can be expressed as a fraction (21/99, or 7/33 simplified)
√225 is 15, which is a rational number
Therefore, the only irrational option is option B. 2π, which is your answer.
Hope this helps!

Step-by-step explanation:
Answer:
x=13
Step-by-step explanation:
Lines that are perpendicular to each other have opposite sign reciprocal slopes. The slope of the x-axis is 0, so the slope of the line will be undefined (vertical)
x = something
A vertical line has the same x-value all the way through, so the y-value will just keep going up.
