Answer:
f(g(x)) = 2/(x^2 +4x)
Step-by-step explanation:
rounding 0.0692494 to 3SF is 0.069
If its a right-angled triangle you can find the third side if the length of the other 2 sides are known. Use the Pythagoras theorem.
If you have 2 triangles which are similar and you know the length of one or more sides of one of them then you can find the lengths of corresponding sides in the second triangle.
The remainder is non-zero, so 
is not a factor of 
(or whatever the given polynomial is supposed to be)
Answer:8m^2n - 32m^2 + 15n^2 - 18mn^2
Step-by-step explanation:
4m x 2mn = 8m^2n
4m x -8m = -32m^2
3n x 5n = 15n^2
3n x -6mn = -18 mn^2
when you add them all together,
8m^2n - 32m^2 + 15n^2 - 18mn^2
