[unborn leaf]

Result:

50

[brittle axle]

Is that correct

[tough mortar]

<5, 10>

[tough mortar]

this is 5 * 10 and not a vector

[brittle axle]

Oh so the answer 5 ,10

Can you help me

To understand

[tough mortar]

yes

[brittle axle]

I will try to do it

[tough mortar]

2u means the values of vector u multiplied by 2

[brittle axle]

,2(-3)

,calc (2)(-3)

[unborn leaf]

Result:

-6

[tough mortar]

which is 2 * 4 for the x value and 2 * 4 for the y value giving you 8, 8 then you just add vector v to your answer which is 8 + (-3) and 8 + 2

[tough mortar]

this would be (4 times v) - u

[brittle axle]

(4)(-3)

,calc (4)(-3)

[unborn leaf]

Result:

-12

[tough mortar]

-12 for the x and the y value would be?

[brittle axle]

,calc (4)(-2)

[unborn leaf]

Result:

-8

[brittle axle]

-11,-8

[tough mortar]

yup, now add vector u to your answer

[tough mortar]

-12

[brittle axle]

-11+1

=-12

,calc -8+-3

[unborn leaf]

Result:

-11

[brittle axle]

-12,-11

Wait

Is it wrong?

[tough mortar]

(-12 -8) + (-3 1)
((-12 -3), (-8 +1))

-15, -7

[brittle axle]

It wrong

I have one more chance to get the correct answer before it takes me to an other question

[tough mortar]
