We say two matrices and
are inverses of each other when
where
is the identity matrix.
So, for and
to be inverses of each other, we should have
.
Let us calculate .
This is clearly not equal to the identity matrix. So we conclude that the matrices are not inverses of each other.
Answer:
2ab + c²
Step-by-step explanation:
Please find attached a diagram of square 5
Area of a triangle = 1/2 x ( base x height)
(1/2 x (a xb) ) x 4 = 2ab
The Pythagoras theorem : a² + b² = c²
where a = length
b = base
c = hypotenuse
a² + b² = c²
a² + 2ab+ b² = 2ab + c²
