Answer 1

Answer:

Step-by-step explanation:

A postulate is a statement accepted to be true without proof. ... Other true statements are geometric postulates and include the ruler, angle addition, and segment addition postulates. Postulates are used particularly in proofs and sometimes in math problems.

q2 =(x + 2y + 4z)²

Using identity,

(a + b + c)² = a² + b² + c² + 2ab + 2bc + 2ca

Here, a = x, b = 2y and c = 4z

(x + 2y + 4z)²

 = x² + (2y)² + (4z)²² + (2×x×2y) + (2×2y×4z) + (2×4z×x)

                   

= x² + 4y² + 16z²+ 4xy + 16yz + 8xz
