If A-B = 13, a's Square - B's Square = 39, then a's square + B's square + 2Ab =?

From A-B = 13, we get a = 13 + B, and substitute a = 13 + B into the square of A-B = 39, we get b = - 5, a = 8. So the square of a + the square of B + 2Ab = 9

How many square meters is 0.39 square kilometers?
How many square meters is 0.39 square kilometers?

1km = 1km = 1000M
1km & sup2; = 1km & sup2; = (1000m) & sup2; = 1000 & sup2; M & sup2; = 1000000m & sup2;
So 0.39 km2 = 390000m & sup2;

If a + B = 3, ab = - 12, what is the square of a plus the square of B (- a-b)?

a²+b²
=(a+b)²-2ab
=9+24
=33
(-a-b)²
=(a+b)²=9
(a-b)²=a²+b²-2ab=(a+b)²-4ab=57
