Hey gorgeous !

misty1212 · Answer

you are being asked to use pythagoras, i.e. compute 
$$(x-7)^2+(2x-10)^2$$ that is all

anonymous · Answer

How do I do that :( ?

misty1212 · Answer

multiply out, combine like terms

anonymous · Answer

Combining like terms like x, and like 7 and 10 ?

misty1212 · Answer

just do it as the nike people say 
start with 
$$(x-7)(x-7)+(2x-10)(2x-10)$$ then grind it til you find it

misty1212 · Answer

not "combine like terms, then multiply" but 
"multiply, then combine like terms"

anonymous · Answer

Ugh I'm so not sure how to do this :( 
How do you multiply those equations ?
