If the above is your question
Cancel 0.5 of numerator and denominator and your question becomes
Squaring both sides
So
I think you can go ahead and solve this and next question
Hello schoolhelpFirst of all, notice that in you can cancel the initial 0.5's to get
Then you need to know that:
- ; and
So
Do the same with the denominator:
and now invert and multiply, and the second equation reads
Substitute into the first equation and solve for , and then .
Do the second problem in a similar way.
OK now?
