The perimeter of an equilateral triangle is 26 centimeters. Find the altitude of the triangle
ioda

We have P = 3 x a (the formula of the perimeter); 26 = 3 x a ; we obtain a = 26/3;

Then, we have  <span>the Pythagorean Theorem in one of two rectangular and congruent triangles :</span>

h² = a² - (a/2)² = a² - a²/4 = 4a²/4 - a²/4 =<span> 3a²/4</span>

It follows that

h = √(3a²/4) = a√3/2 ≈ 0,866*a ≈ 7,5 centimeter.

PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!! I CANNOT RETAKE THIS!!
irina1246 [14]

5x^3 - 4x + 1 = 0 \\\\5x^3-5x+x+1=0\\\\5x(x^2-1)+1(x+1)=0\\\\5x(x+1)(x-1)+1(x+1)=0\\\\(x+1)(5x(x-1)+1)=0\\\\(x+1)(5x^2-5x+1)=0\\\\x=-1\\\\5x^2-5x+1=0\\\\\Delta=(-5)^2-4\cdot5\cdot1=25-20=5

\Delta>0 therefore there exist two real solutions.

In total, there are 3 real roots. But, real roots are also complex roots (doesn't work the other way round!), so there are 3 complex roots.
