How do I work this correctly? I know the answer is 7 but I am doing something wrong.Here is what I have... x+ã(2x-5)=10 x+ã(2x-5)^2=10^2 x+2x-5=100 3x-5+5=100+5 3x=105 x=35 PLEASE HELP!

I am writing a report for Geography about the River Tees . Where the river starts the source is this called the upper course? and where it ends is this called the lower course? thanks for help

In the river tees is the upper course at the begining where the source is and the lower course where the mouth is? thanks

I am sorry, How would I set this problem up?

Okay,If I understand this is what I come up with. square root of 6^2-2^2=x^2 square root of 36-4=x^2 square root of 32=x^2 x=4 square root of 2*2= x=8 square root of 2= approx. 11.3 m

Thanks! :)
