It would lie between 180 and 220
Answer:
10x(2x+1)
Step-by-step explanation:
20x^2+10x
2*10*x*x + 10 *x
Factor out the common terms

1/5 , 3/10 , 0.5
This will help
Answer:
(1)
Multiplying by 3 both sides of the equality you get that

3u is in the Span of the vectors
.
(2)
That's not true, consider the following counter example.

is a linear combination of
but is NOT a linear combination of 
Step-by-step explanation:
(1)
As the hint indicates, you know that

Then, if you multiply both sides of the equality by 3, you get that

And that's it. 3u is in the Span of the vectors 
(2)
That's not true, consider the following counter example.

is a linear combination of
but is NOT a linear combination of
