The Pythagorean theorem is a formula in geometry that states a^2 + b^2 = c^2, where a and b are the lengths of the two legs of a right triangle, and c is the length of the hypotenuse. It is used to find the length of an unknown side of a right triangle, given the lengths of the other two sides.
A fraction represents a part of a whole, expressed as one number over another, while a decimal is another way of expressing a part of a whole, using a decimal point and place value.
When x = 3, y = 2(3) + 5 = 11.
The formula for finding the area of a circle is A = pi*r^2, where A is the area, r is the radius of the circle, and pi is a mathematical constant that represents the ratio of a circle's circumference to its diameter (usually approximated as 3.14).
