Which of the following equations represents the pythagorean theorem?
c = a + b
ab = ba

The theorem is a²+b²=c²
Rewritten it is √(a²+b²) = c

The correct answer is:  " c = √(a² + b²) " .

Explanation:

The Pythagorean theorem is:  a² + b² = c² .

↔   c² = a² + b² ;

Take the square root of EACH SIDE OF THE EQUATION;

→  √(c²) = √(a² + b²) ;

→  c =  √(a² + b²) ; which is one of the two answer choices given; which is correct.

Note:  The other answer choice given:

m = (y₂ − y₁) / (x₂ − x₁) ;  refers to the calculation of the slope of a line; given an equation for a line, in "slope-intercept form"; that is, "y = mx +b" ;  in which "m" is the slope, given the coordinate of two points on the line: 

            →   (x₁, y₁) ;  and:   (x₂, y₂)  ;


which is NOT related to the "Pythagorean theorem" equation.

29. because you will divide each number of months by 12 to find the number of years. which would mean, 5, 12.5, 16, 45, 50, 72.5. which is crazy. anyhow, i think you find the median in the middle. and yea hope your test goes good
