What is the final step in solving this work for c?

a² + b² = c²

3² + 4² = c²

9 + 16 = c²

25 = c²

• Divide both sides by 2

• Take the square root of both sides

• Multiply both sides by 2

• Square both sides

Which equation reflects the right triangle shown?

• x² + 14² = 20²

• 14² + 20² = x²

• 14² – 20² = x²

• x² – 14² = 20²

Which equation can be used to solve for "x"?

• 15² – x² = 21²

• x² + 15² = 21²

• 15² + 21² = x²

• x² – 15² = 21²

Which equation represents this problem?

• 28

  $x^2+16^2=12^2$

• $x^2+12^2=16^2$
  

• $12^2+16^2=\ x^2$
  

• $12^2-16^2=\ x^2$
