You break it down into steps. FIrst do the X's. 5x-3x=2x Then you add 18 to both sides and your equation looks like this 2x=22 Divide by 2 on both sides and x=11
The general form for Pythagoras' theorem is: a² + b² = c² (where c is the longest side).
You already have sides a and b, and to figure out c, you just have to substitute the numbers into the original equation and work it out step by step. Let's substitute a for 17 and b for 24:
a² + b² = c²
(17)² + (24)² = c²
289 + 576 = c²
865 = c²
Square root both sides to work out c:
√865 = √(c²)
c = √865 ≈ 29.41
<span>10, 3, -1, -5, -11 is the answer.
