56 divided by 8 is 7
So they will need 7 tents
I got a hold on hood for the
Answer:
52
Step-by-step explanation:
If u=(a1i+b1j)=(a1,b1) and v=(a2i+b2j)=(a2,b2), then the dot (scalar) product is:
u.v=(a1,b1).(a2,b2)
a1b1+a2b2
u.v=(8,-7).(3,−4)
(8)(3)+(-7)(−4)
24+28=52
$7, I think. I would not be too sure about it, though.
Answer: 37 you just add the two in that case
