where

is the angle between the vectors. You have

The vectors would be orthogonal if the dot product had been zero, but that's clearly not the case.
They would be parallel if the angle turned out to be

or

, but that's also not the case.
So the answer is neither.
Only when any equation you find among those numbers can be simplified into one of the four main equations, wich means you only have four different true statements, and lots of equivalences.
Answer:
24 cars
Step-by-step explanation:
out of 80 toys, 3/5 are buses- 80 * 3/5 is 48 so there are 48 buses
80 - 48 is 32, 32 of the rest of the toys are cars and bikes
we know that there are 3 times as many cars than bikes, so to find out how many cars and bikes there we can do 3n + n, where n is the number of bikes it also equals 4n
32 = 4n; n = 8
there are 8 bikes, so there are 24 cars
Answer:
Step-by-step explanation:
Here you go mate
Step 1
8m+4n+7m-2n Equation/Question
Step 2
8m+4n+7m-2n Simplify
8m+4n+7m-2n
Step 3
8m+4n+7m-2n Combine terms
(8m+7m)+(4n+-2n)
Step 4
(8m+7m)+(4n+-2n) Add them
answer
15m+2n
Hope this helps
