Find the area of the region satisfying the inequality x^2 + y^2 <= 4x + 6y+13 + 10x +2y
+9674 When you move every term to the left-hand side, you get \(x^2 + y^2 - 14x - 8y - 13 \leq 0\).
Complete the squares and you will get \((x - 7)^2 + (y - 4)^2 \leq 78\).
So this is actually just the area enclosed by the circle centered at (7, 4) and with radius \(\sqrt{78}\). Can you take it from here?
