Answer:
Step-by-step explanation:
To add these vectors together, we have to "glue" them together.
Let's call the vector with the length of 2 <em>A </em>and the one with length 4 <em>B.</em>
Imagine you can grab vector A with your hands and move it to the end of B (it would look like the image that's annexed)
Now imagine that we made a triangle from that, what we want to know is the hypotenuse of that triangle!
We know that when we want to find the hypotenuse of a triangle, we can use Pythagoras theorem:
Let's plug in the known values (the length of the vectors) and solve this
Good luck!
F(x)=x²+2x-1 and g(x)=2x-4 <span>2f(x)-3g(x)=?
</span>2f(x)=2*(x²+2x-1)=2x²+4x-2
3g(x)=3(2x-4)=6x-12
2f(x)-3g(x)=(2x²+4x-2) - (6x-12)= 2x²+4x-2 - 6x+12 =2x²-2x +10
<em>2f(x)-3g(x) = 2x²-2x +10</em>

Hope this helps.
Answer:
No. Dividing by 0 is not rational, no number works.
