Answer 1

Step-by-step explanation:

Galvanisation is a method of protecting steel and iron from rusting by coating them with a thin layer of zinc. The galvanised article is protected against rusting even if the zinc coating is brokenGalvanisation is a method of protecting steel and iron from rusting by coating them with a thin layer of zinc.

Answer 2

Step-by-step explanation:

Given

x³ -3x² + 3x + k it has zero = 3

so,

the value of polynomial at 3 should be = 0

p(x) = x³ -3x² + 3x + k = 0

p(3) = 3³ -3(3)² + 3(3) + k = 0

= 27-27+9+k = 0

= 9+k = 0

k = -9
