could you please explain how you got that answer

hi, 

could you please explain how you got that answer

Thank you Melody! 

So that would mean

the second one is 5-3 =2 

the third is 9-8 = 1

right?

It would be

3(v•u) - 2(w•u) = -3(u•v) + 2(u•w) = -3x3 + 2x4 = -9 + 8 = -1

right?

Hi Alan, I was just wondering. The questions say that a and b are complex numbers but your solutions are not complex numbers. 

Thank you so much Alan!

Thank you Melody!

Thank you so much ilorty!

I got 14 for the first part, is that correct?

thank you so much, but could you show me how you got the answer, rather than just the solution?

I have figured out the answer which is, 3,3,4,3,2,4

thank you so much!

Thank you so much Alan! 

thanks! ill take a look at it!

Hi,

there is a website called desmos, desmos.com/calculator, a graphing calculator that will help you graph that problem. 

I haven't learned that yet, could you please help me with the problem?

thank you so much!
