Answer:
x = - 9, x = 0, x = 7
Step-by-step explanation:
Given
 x(x - 7)(x + 9) = 0 ← in standard form
 x(x - 7)(x + 9) = 0 ← in standard form
Equate each factor to zero and solve for x
 x = 0 ⇒ x = 0
 x = 0 ⇒ x = 0
x - 7 = 0 ⇒ x = 7
x + 9 = 0 ⇒ x = - 9

A^2 + B^2=C^2 so there for the hypotenuse (13^2) - (5^2) will give you the last side
