Friction produces heat because it causes the molecules on rubbing surfaces to move faster and have more energy
Answer:
Given below
Step-by-step explanation:
The algebraic identity is (a-b)^2
= a^2 + b^2 - 2ab
So it'll be,
(x-4)^2
= x^2 + (4)^2 - (2)(x)(4)
= x^2 -8x + 16
or x^2 +16 -8x
27.
Volume = length*width*height
So 3*3*3=27
