51/9––>17/3=5 2/3

Oh, this is really easy!
Okay so the formula for the pythagorean theorem is a²+b²=c<span>²
So it doesnt really matter whats a or b
So take 21</span>²+15²=c<span>²
That ends up being 441+225=c</span><span>²
so next take 441+225 and that equals 666 then you have to find the square root so the square root of 666 is 25.81
S the answer is 25.81 </span>
P=2(k+w)
p=2k+2w
(subtract 2k from both sides)
p-2k=2w
(divide 2 from both sides)
p/2-k=w
w=p/2-k thats what i got. hope this helps love! :)
