Given a triangle with two sides measuring 12 cm and 16 cm, which of the following cannot be a possible length for the third side?

The area (in sq, units) of the triangle formed by the graphs of 8x + 3y = 24, 2x+8 = y and the x – axis is:

If x −y =4and xy =45,thenthevalueof x ³ −y³is:

If x + y = 2 and 1/x + 1/y = 18/15, then find the value of (x³ + y³)?

22% of ‘x’ is equal to 66% of ‘y’, then find the value of x: y.

If y + 1/y = 2 then find y¹¹⁷ + 1/(y¹¹⁷)

if a² + b² + c² = 2(4a -5b -9c)-122 , then a-b-c = ?

If a – b – c = 0, then the value of (a² + b² + c²)/(b + ac) is:

If 5x - 13xy + 6y = 0, find x : y.
