Answer:
(2) 6x^2+40x +50
Step-by-step explanation:
(4x+10)*(2x+5) = 8x^2 +40+50
minus 2x^2
=6x^2 +40 +50
Answer:
a
Step-by-step explanation:
edge 202011
If
is a homomorphism, then we have, for every ![g,h \in G](https://tex.z-dn.net/?f=g%2Ch%20%5Cin%20G)
![\phi(gh) = \phi(g)\phi(h)](https://tex.z-dn.net/?f=%5Cphi%28gh%29%20%3D%20%5Cphi%28g%29%5Cphi%28h%29)
Since G is abelian, we have
, and thus ![\phi(gh)=\phi(hg)](https://tex.z-dn.net/?f=%5Cphi%28gh%29%3D%5Cphi%28hg%29)
But we also have
![\phi(gh)=\phi(g)\phi(h)=\phi(h)\phi(g)=\phi(hg)](https://tex.z-dn.net/?f=%5Cphi%28gh%29%3D%5Cphi%28g%29%5Cphi%28h%29%3D%5Cphi%28h%29%5Cphi%28g%29%3D%5Cphi%28hg%29)
which proves that G' is abelian.
In other words, for every
, you have
, because there exist
such that
, and you can think of
as
, and of
and ![\phi(h)\phi(g)](https://tex.z-dn.net/?f=%5Cphi%28h%29%5Cphi%28g%29)
Then, you observe that
because they mean
, and
by hypothesis, because G is abelian.
Answer:
√1762
Step-by-step explanation:
Square root of 1762
How?
Well 41^2+9^2=c^2
1681+81=c^2
1762=c^2
c=√1762
