Hey I saw your new question.... If you just point about the points A and B in the graph I will gladly help you.
Answer:
let the two numbers are x & y
x+y=30...eq(1) &x-y=12....eq(2)
x=30-y then put in the eq(2)
30-y-y=12
30-2y=12
-2y=12-30
-2y= -18
y=9 then we put this answer in to eq(1)
so,x+y=30
x+9=30
x=30-9
x=21
so, the two numbers are (21,9)
This means that
+- 6 < √42 < +- 7
hope it helps
