Question 52494
{{{x - sqrt(x) = 0}}}
{{{x = sqrt(x)}}}
{{{x^2 = x}}}
{{{x^2 - x = 0}}}
{{{x(x - 1) = 0}}}
{{{x = 0}}} and {{{x = 1}}}
Now, a right triangle has two legs: {{{a}}} and {{{b}}} ....
And a hypotenuse: {{{c}}} ....
a = 3
b = 4
c = ?
{{{c^2 = a^2 + b^2}}}
{{{c^2 = 3^2 + 4^2 = 9 + 16 = 25}}}
{{{c = sqrt(25)}}}
{{{c = 5}}}
The hypotenuse is 5 feet long.
