Answer:
length= √[ (a-c)^2 + (b-d)^2 ]
Step-by-step explanation:
Remember the properties of logarithms. If you have ln81, you can pull out the power of two (9^2) and have 2ln9. Also, you could do ln9 + ln9 because 9*9=81 and ln9*9 = ln9 + ln9
With these properties, you can get 3lnx+2lny, which is 3u+2v according to the answer.

Answer:
10
Step-by-step explanation:
p² +3q
= 2² +3*2
=4 + 6
=10
To find the cross product, you can set this up as a proportion. Please see the attached paper for one of the proportions you could use.
You would then multiply the numbers that are diagonal from each other.
You would have 21(8) = 12x or
168=12x.
