Answer:
its option B: r=(3xy)/(x-2y)
So this is going to be using proportions, which in this case is going to be 
Firstly, cross-multiply to get 
Next, just divide 18 on both sides, and your answer will be 
, or the last option.
Answer:
= 1/3 * sqrt(1/2)
Step-by-step explanation:
sqrt(1/18)
We know that sqrt(a/b) = sqrt(a)/sqrt(b)
sqrt(1/18)
sqrt(1)/sqrt(18)
1/sqrt(18)
We also know that sqrt(ab) = sqrt(a) sqrt(b)
1/sqrt(18) = 1/ sqrt(9)sqrt(2)
= 1/(3sqrt(2))
= 1/3 * 1/ sqrt(2)
We know that sqrt(a/b) = sqrt(a)/sqrt(b)
= 1/3 * sqrt(1/2)
Answer:
3 and 4
Step-by-step explanation:
proportionally it is the same shape and 2/1 is 2 so that's your scale factor
Answer:
Everything in the option.
When you know what you are doing and what you are saying then you can be able to convince your audience.
